　　 Aston martin, which rarely releases new cars, seems a little busy in 2022. In addition to the final version of Vantage V12, on February 1st, we will welcome a brand-new DBX (Configuration | Inquiry) high-performance SUV, which will become "the most powerful luxury SUV in the world". Not surprisingly, this new car will be DBX S, probably powered by V12 developed in aston martin, instead of the 4.0-liter twin-turbo V8 engine from Mercedes -AMG currently used by DBX, DB11 and Vantage.

　　 According to the officially released Change is Coming preview video, some rims, body and interior of the new aston martin DBX S are displayed, and at the same time, we can appreciate the wonderful sound of the new car. More importantly, the release date of the new car has also been officially confirmed, and it will be launched worldwide on February 1, 2022. It is worth mentioning that the video description also wrote "Change is coming. Power talks。 The world’s most powerful luxury SUV。 01.02.22 (Change is just around the corner, and performance is king. Please look forward to the arrival of the world’s most powerful luxury SUV on February 1), which makes people can’t help but expect the new car to have unparalleled power performance.

　　 At present, aston martin DBX is equipped with a 4.0-liter twin-turbo V8 engine from Mercedes -AMG, and its maximum output power is 542 HP (405 kW) and 700 Nm respectively. China also provides a light hybrid power of a 3.0-liter turbocharged inline six-cylinder engine because of tax reduction. Although DBX S may extend the enhanced version of the V8 engine of AMG, it is more likely to be its own 5.2-liter twin-turbocharged V12 engine. Previous spy photos show that the sound of DBX S is similar to that of other V12 coupes DB11 and DBS Superleggera in aston martin. If the goal of DBX S is the most powerful luxury SUV, challenging competitors such as Porsche Cayenne Turbo GT with 631 horsepower, Bentley Tim Yue Speed with 626 horsepower, BMW X5 M Competition/X6 M Competition with 617 horsepower, Mercedes -AMG GLE/GLS 63 S with 603 horsepower and Rolls-Royce Cullinan with 600 horsepower, then V12 will undoubtedly be the biggest fire protection to achieve this goal.

　　 Aston martin can now have AMG-derived V12 engines with various power adjustment levels, ranging from 600 horsepower of DB11 to 715 horsepower of DBS, and 630 horsepower of DB11 AMR. However, DBX, a 4.0-liter V8 with 542 horsepower, can also be adjusted to increase the total power output, just as Mercedes AMG-GT Black Series can be upgraded to 720 horsepower with a flat crank. Of course, it will be simpler and cheaper for DBX to install a V8 engine with stronger output than V12, and it is obvious that the V8 engine is used in the preview video.

　　 Therefore, how much power DBX S needs to become the most powerful luxury SUV in the world depends on aston martin’s own definition of competitors. The 707-horsepower Jeep Grand Cherokee Trackhawk and 710-horsepower Dodge Durango SRT Hellcat have more than 700 horsepower, but we don’t expect new cars to surpass them, because these two American models are not luxury SUVs; The most powerful competitor, Porsche Cayenne Turbo S E-Hybrid, has only 671 horsepower plug-in hybrid transmission system.

　　 Previously, aston martin DBX S has been tested at newberg Forest Circuit, and its design has been exposed in advance. The new car will be more aggressive than the ordinary version, with a larger grille occupying the visual focus at the front, canceling the horizontal lath shape of the ordinary version and replacing it with a black grid pattern; The front bumper has been redesigned around the new grille, with a single deep air inlet that spans the entire width of the front and rises on both sides of the main radiator grille. The increase in the size of the air inlet indicates the need to cool more powerful power than before. A set of four-outlet tailpipes replaces the double-outlet setting of the ordinary version; Duck tail short tail and full width light bar and roof spoiler are still retained.

　　 In addition, DBX S will also use the improved adaptive air suspension settings to make a more sporty adjustment and improve the steering directivity. DBX S will kick off the new DBX model. Starting from the end of 2022, aston martin will also launch a six-cylinder light hybrid model, and plug-in hybrid vehicles are also in the pipeline. "DBX is about to enter the next chapter, which will set new performance standards. Are you ready for the world’s most powerful luxury SUV? " Aston martin said at the end of the preview video. For more information about DBX in aston martin, please pay attention to the follow-up reports. (Source: Aston Martin Compilation: Kishi.W)

Moon cakes of Yunnan University.

Moon cakes of Kunming University of Science and Technology.

The Mid-Autumn Festival is getting closer and closer. In the R&D center of Yunnan Dairy Association in Yunnan Agricultural University, a moon cake team composed of more than 20 people is busy. With the surge of orders, team members have to make 300 to 400 mooncakes with milk fans every day. These moon cakes with the characteristics of Yunnan Agricultural University are not only beautifully designed and unique in taste, but also contain a strong Yunnan flavor.

Not only Yunnan Agricultural University, Yunnan University, Kunming University of Science and Technology and other universities have also launched customized moon cakes to show the innovative spirit and humanistic feelings of college teachers and students with traditional cuisine.

"Yunnan flavor" goes out

Students from the Moon Cake Team of Yunnan Agricultural University come from the innovation and entrepreneurship team of food resources and dairy science. In the operation room, they have a clear division of labor, and they are making mooncakes with unique characteristics of Yunnong in an orderly manner according to the process.

First, the raw milk fan is cut into pieces, fried in an oil pan, salvaged for special deoiling treatment, then ground into pieces, and added with cranberries and honey to make a unique milk fan filling, and then wrapped by students by hand. "In order to prevent the milk fan from getting oily after it is left for a long time, we have specially added the deoiling link, so that the moon cake tastes better and is more healthy." Team member Dong Xiaozhu said.

This year, Yunnan Agricultural University launched two kinds of milk fan moon cakes, namely, honey crisp milk fan moon cake and milk fan crisp cake moon cake. In the hands of students, Taoshanpi was pressed into colorful mooncake skins. They weigh the stuffing accurately, put it into the dough according to a certain proportion, then knead it, press it into shape, and finally pack it out of the oven. The words "Yunnong" and "1938" are printed on the small moon cake, and there are two long ears of wheat, which fully show the characteristics of this agricultural college which was founded 85 years ago.

According to Huang Aixiang, the instructor of the innovation and entrepreneurship team of food resources and dairy science and a professor at the College of Food Science and Technology of Yunnan Agricultural University, milk fans have a long history and rich nutrition. During the Tang Dynasty, Dali people had the custom of making milk fans from Deng Chuan. The moon cakes made from milk fans have a strong Yunnan flavor.

Huang Aixiang and his classmates have been committed to the innovative research and development of dairy products, in order to let more people "see" Yunnan dairy products, "see" Yunnan cuisine and "see" Yunnan’s high-quality agricultural special products.

Like Yunnan Agricultural University, Yunnan University of Traditional Chinese Medicine has "sent out" Yunnan elements through innovation. This year, Yunnan University of Traditional Chinese Medicine launched four kinds of medicated moon cakes. Polygonatum sibiricum added to medicated moon cakes is Polygonatum yunnanense produced in Yunnan.

"The school has been making medicated moon cakes since 2016. We asked Chinese medicine experts to select Chinese herbal medicines for both medicine and food to match, constantly adjust the taste, and launched a medicated moon cake with low sugar and good taste. " According to the relevant person in charge of Yunnan University of Traditional Chinese Medicine, the series of medicinal moon cakes launched this time is an innovative attempt to develop Polygonatum, which has four flavors: Polygonatum odoratum, Polygonatum wuren, Polygonatum kumquat and Polygonatum odoratum with cloud legs.

Gifts for teachers and students during the festive season

In Yunnan, there are many colleges and universities like Yunnan Agricultural University and Yunnan University of Traditional Chinese Medicine that "carve" Yunnan flavor, hometown elements and school characteristics on moon cakes.

"A hundred schools of thought will benefit the whole world", and Yunnan University printed the school spirit on moon cakes. Seeing this moon cake, Yunnan University students naturally raised their feelings of loving the school. These moon cakes are made by the Catering Service Center of Yunnan University Logistics Service Group and will be given to students at school. This is also the school’s 18 consecutive years of homemade moon cakes for free to students.

Since 2006, in order to alleviate students’ homesickness, Yunnan University has given students free moon cakes to let them feel the warmth of this big family. Different from previous years, this year’s catering service center made exquisite gift boxes, which printed the beautiful scenery of the school’s late green garden on the boxes, creating a good holiday atmosphere. This year, the Catering Service Center plans to make 33,000 mooncake gift boxes. Each mooncake gift box contains 2 ham mooncakes, 1 Wuren mooncake, 1 Yunnan crispy coconut mooncake and 1 hawthorn mooncake.

Kunming University of Science and Technology Logistics Service Center Food Service Center produced Kungong characteristic Wenchuang moon cake, which was also launched, and was called drop-dead gorgeous in the moon cake by the students. Wenchuang moon cake of Kunming University of Science and Technology takes the shape of a full moon, takes the school emblem as the pattern, is unique, and prints the seal of the exclusive Kungong. In terms of fillings, there are fragrant peach fillings, sweet poplar nectar fillings, sweet litchi fillings, and strong coconut cheese fillings, and there is always one that can meet the needs of taste buds. In addition to Wenchuang moon cakes, traditional moon cakes are indispensable. Yuntui, red bean paste, Wuren and egg yolk lotus seed paste are all the favorites of Kungong workers.

This year, Yunnan Institute of Technology continued to launch the "School Emblem Moon Cake", with the school emblem and school year printed on the front of the moon cake. There are three flavors of mung bean, red bean and pineapple, which are the most popular among teachers and students of Yunnan Institute of Technology. According to the relevant person in charge of the college, the meaning of red bean moon cakes is the most special, because red beans are also called acacia beans, and students come from all corners of the country. I hope red beans can pin their love for acacia. Since 2017, the school has made a "school emblem moon cake" and sent it to new students, hoping to let everyone feel the care of the school.

　　Refund increased. The Wandering Earth was attacked by piracy.

　　0.5 yuan to 5 yuan can watch Chinese New Year movies, and cat-eye movies show that the number of refunds in The Wandering Earth has increased; The National Copyright Administration says piracy is being curbed.

　　It took The Wandering Earth only four days from the release to the appearance of high-definition piracy.

　　On February 5th, Chinese New Year movies such as The Wandering Earth, Crazy Alien and New king of comedy came. Among them, The Wandering Earth is regarded as the milestone of China’s sci-fi movies, which has aroused the attention of the whole people. The Beijing News reporter found that on the first day after the release of these films, there was a gun version of the video; On February 8th, all the high-definition video resources of movies being shown were already available online.

　　The Beijing News reporter contacted a number of people who sold "high-definition movie resources" and found that the prices of the above-mentioned movies ranged from 0.5 yuan to 5 yuan, and the playing forms mainly included direct viewing by sharing links with network disks and direct viewing from websites. In addition, movies and videos purchased from multiple channels were all advertised as barrage in a casino in Macau.

　　On February 10th, the National Copyright Administration issued a statement, saying that it would severely crack down on online infringement and piracy, protect excellent domestic films, and hand over serious infringement and piracy elements to the public security department to take criminal measures to severely crack down.

　　Deng Hongguang, a professor of intellectual property at Southwest University of Political Science and Law, told the Beijing News reporter that "online piracy is often copied by people by recording movies and then uploaded to the Internet. Its behavior infringes the copyright owner’s right to copy and disseminate information on the Internet, and may be sentenced to fixed-term imprisonment of not less than three years but not more than seven years and fined".

　　Macao casino advertisement appears in pirated video.

　　On February 5th, the Spring Festival Lunar New Year movie came, and on February 6th, Xiaokang (a pseudonym), a seller selling movie resources online, got the gun version resources of Crazy Alien and New king of comedy.

　　The Beijing News reporter saw in a well-off circle of friends that these movie videos were directly "stolen" in the cinema, so the picture was slightly shaky and unclear. In this regard, Xiaokang said that it can be "free to make up" after the high-definition resources are released.

　　On February 8th, a well-off circle of friends appeared "HD Video of 2019 Spring Festival Lunar New Year movies", including The Wandering Earth, Crazy Alien, Flying Life, New king of comedy, and Clean Government. The HD version of the above films is sold as a movie in 5 yuan, which can be watched directly through the network disk.

　　In the hands of another seller of movie resources, the price was pressed even lower. The above-mentioned films, together with Pu Songling, Piggy Peggy for the New Year, are packaged and sold at the price of 4 yuan. On average, you only need to ask 0.5 yuan for a movie. On February 8 th, the movie released in the Spring Festival file was already caught by pirates, which was only the fourth day after the movie was released.

　　Xiaokang told the Beijing News reporter that when new movies are released, what they get is generally gun version resources, not HD. Therefore, this time, when the New Year’s film was released in high definition, it "sold a lot".

　　The Beijing News reporter noted that since February 8, the pirated broadcast resources of HD version have flooded the whole network. There is even a "resource website" that directly plays movie videos for free. On February 10th, the Beijing News reporter found in a resource station provided by a pirate that you can directly watch The Wandering Earth in HD1080P online for free as long as you log in to the website. The website can even log in and watch through WeChat scan code.

　　In this regard, The Wandering Earth producer Gong Geer told the media a few days ago that the staff in The Wandering Earth did not have time to celebrate the rising box office, but spent almost all their energy on complaining and blocking piracy.

　　On February 8th, Gong Geer said in his personal Weibo that all the anti-piracy links suggested by netizens have been reported and blocked, but for technical reasons, some of them are blocked quickly and some need some time. Everyone’s private messages are not energetic enough to reply one by one. "My anti-piracy team and I are especially grateful for your support. Please continue to cheer!"

　　On February 10th, the National Copyright Administration said that serious infringement and piracy will be handed over to the public security department to take criminal measures to crack down. On February 11th, Weibo, the official of the National Copyright Administration, reported that in recent days, through the joint action of various departments and rights holders, the pirated transmission of cinema films for the Spring Festival has been curbed to some extent.

　　Yesterday, the Beijing News reporter found that WeChat has banned the WeChat viewing link of the aforementioned pirated websites because it contains "infringing content".

　　Pirates drain through social networking sites and online shopping platforms.

　　Where do the high-definition movie resources of the Spring Festival file come from? Xiaokang told reporters that he downloaded from the "resource number" and "website with resources".

　　The Beijing News reporter found that these "resource numbers" are WeChat official account, which often publish some film and television resources. However, many "resource numbers" are not the direct source of film leakage. Because the threshold of pirated video is extremely low, every buyer who downloads pirated video can directly monopolize it and become the next seller, so most pirates are the lower participants in the pyramid of pirated video industry chain, not the "source" of film leakage.

　　Zhao Hu, a partner of Beijing Zhongwen Law Firm, told the Beijing News that the source of the film leak is complicated. "Because a movie has to go through several hands from production to final release, in addition to production, there are also corresponding departments of the country, corresponding cinemas and distributors, and there will be a movie master, and many people will handle it. Any place that is handled may be the source. "

　　But it is very easy to become a pirate. Xiaokang told the Beijing News reporter that it only costs 188 yuan.

　　"When we recruit an agent and pay an agent fee of 188 yuan, we can get the’ resource number’ and the reliable website, and get all the resources updated for free. You can watch any movie you want from it."

　　It is worth noting that the Beijing News reporter found that these "high-definition videos" always drift across the advertising barrage of a casino in Macau from time to time, and watch the movie resources in the above three ways, and the advertising barrage appears in different ways.

　　Xiaokang said that his drainage method is to search for relevant Weibo or videos by keywords on platforms such as Weibo and bilibili, and then post advertisements in the comment area. Advertising language will generally be "high-definition resources plus WeChat XXX", and in order to avoid censorship, letters or homophones will be used instead of movie names. The Beijing News reporter found that although such comments may attract buyers, they often attract criticism and even be reported. For example, in bilibili, a video comment area called "The Wandering Earth’s overseas broadcasts have been well received by foreign netizens", after someone posted a drainage advertisement below, some netizens commented that "piracy was promoted and reported".

　　In addition to social networking sites and various video sites, online shopping platforms have also become one of the main battlefields for pirates to drain. On February 11th, the Beijing News reporter found a number of sellers selling movie resources after searching for "movie" on idle fish. One of the sellers said that he sold "How about a movie for the New Year? Interested messages". After the reporter left a message, he was told that he could take pictures of the goods directly on the idle fish, and then send a link to the network disk through QQ to watch.

　　Zhao Hu said that piracy is very harmful to the pirated links of popular movies, because the movie is in the release period and its income mainly depends on the box office. If there is a link, it will have a substitution effect, which will have an impact on the box office, which is a very direct damage.

　　The Beijing News reporter inquired about the box office in The Wandering Earth through Cat’s Eye movies, and found that although the box office in The Wandering Earth rose steadily due to the rising word of mouth, on February 7th, the number of large-scale refunds for the movie was 124,000, while on February 8th and 9th, the number of large-scale refunds for the movie increased slightly, with 143,000 and 146,000 respectively.

　　Lawyers said that serious pirates may be sentenced to imprisonment.

　　Deng Hongguang, a professor of intellectual property at Southwest University of Political Science and Law, said that piracy is essentially the pursuit of personal interests. As long as it is driven by sufficient interests and the risk of this behavior is less than the income, it is difficult to fundamentally eliminate this piracy. If we say prevention, first of all, we should truly realize that "law enforcement must be strict and violators must be prosecuted", thus reducing the psychological expectation of pirates to take risks; The second is to increase the supervision obligation of the platform and require the platform to provide relevant infringement information.

　　Zhao Hu, a partner of Beijing Zhongwen Law Firm, told the Beijing News reporter that the fight against piracy is divided into two aspects: beforehand and afterwards. "In advance, the state organs that have access to the film manage their staff well, and the producers and project parties of the film sign confidentiality agreements to prevent leakage. Afterwards, regardless of infringement or crime, it is necessary to use legal weapons to actively defend rights and let pirates pay the corresponding price. It would be better if they could find the corresponding source. "

　　"China’s copyright law stipulates that other people’s works may not be used in this way without authorization. In addition, if the circumstances are serious, it will constitute a crime of copyright infringement. In other words, if the illegal income is large, or other serious circumstances, it may constitute a crime of copyright infringement and may be sentenced to fixed-term imprisonment of not more than three years. If it is particularly large, it may be fixed-term imprisonment of not less than three years and not more than seven years. " Zhao Hu said.

　　Pirated movies are only a small part of the income of pirates. Xiaokang revealed that because the resources of new movies are not high-definition, most of them are gun versions, and basically "not much to buy", his main income from selling movie resources comes from "restricted" movies that are not allowed to spread. The method of obtaining resources is exactly the same as that of cinema movies, but more people often buy them.

　　In this regard, Deng Hongguang said that as long as other people’s movies are pirated, whether it is a hot movie or a classic movie that has already been played, whether it is a domestic movie or a foreign movie, its behavior is the same in law, which constitutes infringement of copyright. Those who commit serious acts shall be investigated for civil, administrative and criminal responsibilities.

　　"Playing cartoons and film reviews that are explicitly prohibited by SARFT from spreading can be punished from illegal business operation and dissemination of obscene articles. For example, according to the provisions of the Law on Public Security Administration Punishment, anyone who uses computer information networks, telephones and other communication tools to disseminate obscene information shall be detained for more than 10 days and less than 15 days, and may be fined less than 3,000 yuan; If the circumstances are minor, they shall be detained for less than 5 days or fined for less than 500 yuan. " Deng Hongguang said. (Reporter Luo Yidan, liang chen)

Xiaomi Leijun: Xiaomi car does not lose Tesla Model 3, so the pricing can’t be too cheap.

On the evening of July 19th, at Lei Jun’s annual speech in 2024, Lei Jun, chairman of Xiaomi Group, said that Xiaomi Automobile Factory could only stop the cars produced in three days, and he was afraid that he would not be able to sell them, and he was afraid that he would not be able to sell them enough. "Xiaomi car has no retreat, just like a pawn crossing the river, it can only rush forward desperately." Lei Jun said that the goal of Xiaomi Automobile at the end of 2024 is to deliver 120,000 vehicles. In terms of pricing, Lei Jun said that many people were not optimistic about Xiaomi’s new car at that time, and many employees within the company also lacked confidence. However, he insisted that Xiaomi’s new car does not lose Tesla Model3, so the pricing should not be too cheap. (SSE)

Lei Jun responded that Xiaomi Automobile did not OEM or acquire.

Lei Jun said, "More than three years ago, many friends advised me that you were already late. Just get out of the car and find a foundry. Don’t do everything yourself. At the beginning, we thought about both looking for OEM and acquisition, but it didn’t take long for us to make up our mind to start with the core technology and never try to take shortcuts. Why? Because we suffered a big loss 14 years ago. When Xiaomi started his business, it was a light model, starting with model innovation. The initial speed was very fast, but the foundation was not solid. Later, he encountered many setbacks. Up to now, I feel that we are still making up lessons. So when we started our business again, we decided not to take shortcuts, not to buy or OEM, and to start from the core technology. Make ten times the investment and seriously build a good car. " (Sina Technology)

Lei Jun once rejected the $10 billion valuation of Xiaomi Automobile.

Lei Jun responded at the speech site why Xiaomi Automobile didn’t take out independent financing and go public independently. He said that there were indeed several VCs offering prices for Xiaomi Automobile. At that time, because the market was particularly hot, the valuation was 10 billion US dollars. However, Lei Jun refused after much deliberation. "Because the cycle of building a car is very long, if we take other people’s money. It is almost impossible to keep the same idea for a long time. Moreover, a large number of talents are built inside Xiaomi, and the technology can be directly used. I am very, very clear. I think it is very difficult to build a car. I can’t do it alone. " Lei Jun said, I need the unreserved support of everyone in Xiaomi Group. I hope everyone can go all out and build a car together, so we have a chance of winning. So in the end, we decided that Xiaomi will do all his own money and take all his own risks. As long as we can do the car well, we will not hesitate. (Sina Technology)

Lei Jun said in the video, "Recently, I have become the object of many people’s research, saying that I can engage in traffic, which is very powerful. In fact, this makes me a little dizzy. For example, it was actually quite simple to open the door for the owner some time ago. I just wanted to thank our owner, but I really didn’t expect it to be’ 100 billion CEO opens the door for me’. This matter is particularly hot on the Internet. " In addition, Lei Jun also said that he was a little afraid of society and was actually called a "conspicuous bag". He said that he was also very puzzled and gave an analysis: "It is estimated that if I love tossing, it will inevitably be a bit conspicuous." (Sina Finance)

Audio Overview of Mainstream Music Inventory in 2016

　　　　In fact, I am very happy to write this inventory, and finally write about the audio, because I not only experienced the mobile phone scheme, but also listened to the eight mainstream HiFi music phones in 2016, and my ears were almost polished into golden ears. However, this issue will not tell you too much about the evaluation of sound quality, but will talk about the HiFi music phones that I think are the mainstream this year by way of comments, and then I will make a report on the HiFi mobile phone market next year.

　　　　In this issue of 2016 mainstream music mobile phone inventory, the author follows the following points:

1. Mobile phone brands are familiar to everyone.

2, with independent chip bonus.

　　　　In fact, these two points are also the characteristics of a music HiFi mobile phone. Big brands will have good technology research and development. In fact, the most important thing is the use of chips and sound tuning. You must know that some HiFi audio chips are completely customized for mobile phones, which requires the common optimization ability of chip manufacturers and mobile phone manufacturers; In addition to the chip, you need a Andhadhun. The author’s understanding of Andhadhun is to use relevant acoustic principles to optimize the chip and mobile phone lines (of course, this needs to be combined with architecture and line analysis) to make the sound more real and natural.

Figure Reference Table of Mobile Phone Release and HiFi Music Mobile Phone Release from 2013 to 2016

　　　　In fact, what makes the author very happy this year is that 85 mobile phones are music phones, and the music part was mentioned more or less at the time of release. This year, there are 835 mobile phone models on the market, accounting for 10.2%, which is still an increase compared with last year. In 2015, the number of released mobile phones was 815, of which 45 were music phones, accounting for 5.5%. In 2014, this number was still decreasing, with 900 mobile phones released, including 46 music mobile phones, accounting for 5.1%; In 2013, 863 mobile phones were released, including 28 music phones, accounting for 3.3%.

Figure HiFi music mobile phones accounted for the percentage of all mobile phones sold in that year.

　　　　From this point of view, manufacturers are constantly paying attention to the future development of music mobile phones. It is predicted that in 2017, HiFi music mobile phones will become an area that manufacturers will compete for, because there are constantly traditional HiFi chip manufacturers customizing chips for mobile phones. In fact, mobile phones that use HiFi chips alone can also be excavated from music mobile phones. This number is also constantly rising.

　　　　Therefore, in view of this inventory of music mobile phones, the author will be divided into two parts.Today, this part is called "Mobile Phone Playing HiFi 2016 Mainstream Music Mobile Phone Inventory", which is to let readers know about the release of music mobile phones from 2013 to 2016 first, and use charts to give readers a clear understanding. After that, I will give readers an inventory of the music mobile phones that I think are excellent this year, and have a simple understanding.

　　　　In the second part, I will put some very important parameter tests in the next topic, and I will use this part.Actual parameter sumActual hearing senseGive the reader a clear picture. The test platform will choose RMAA, which takes some time to adjust and prepare, and gives a more comprehensive and objective analysis combined with the sense of hearing.

　　　　If you want to be less laborious, you can read this simple inventory and have a general understanding of this year’s HiFi music mobile phone.

HiFi mobile phone pioneer　

vivo　　

　　A scheme that has been developed for more than two years is used: -Fi3.0 architecture. Dual ES9028, triple OPA1612, and independent decoding and amplification of left and right channels are adopted, with dual clock crystal oscillator and secondary power supply. Compared with the ES9018K2M (signal-to-noise ratio of 127dB, distortion rate of -120dB), which is jointly customized and developed by vivo and ESS, it has been widely used, and adopts QFN packaging method. ES9028Q2M, according to the official introduction of ESS, the signal-to-noise ratio of the chip is as high as 129dB, while the distortion rate is -120dB. The data can be said to be excellent.

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　Introduction to ESS9028 (fromESSOfficial website)

　　　　At the same time, a dual channel is used in the mobile phone, one channel is ESS9028, and then the left and right channels are decoded separately through OPA1612. The advantage of this is that the crosstalk interference can be minimized and the overall parsing ability can be improved.

　Interpretation of sound quality chip (picture taken from vivo network)

Summary:

　　　　In fact, the most important sound of this mobile phone is the consistent feature of ES9028: outstanding resolution, relatively large thrust of sound in the mobile phone, and general headphones will be full, so there will be no big problems in this respect.

Classical sound first choice　

　　　　ZTE is the one I like very much, especially the front of the top version. The upper and lower materials of walnut can show a noble workmanship. In fact, the author has already evaluated the sound quality of this mobile phone before, and this time I just want to review it with readers. Of course, we must pay attention to the audio configuration of the mobile phone: AKM4490+AKM4961.

　　　　Let’s take a brief look at the chip promotion page of the chip manufacturer

Chip introduction (from ESS official)

　　　　AK4490EN is an ideal audio chip for mobile devices. It supports high bit rate input PCM 32BIT/768KHz source output, and also supports high-specification 11.2MHz DSD files.

Chip introduction (from ESS official)

　　　　AKM’s advanced DAC chip AK4490EN and top DSP series AK4961. K4961 further integrates ADC into the interior, in other words, it adopts independent ADC+ independent DAC+ independent amplifier, and has high-quality recording and sound playback processing ability in AK4961 chip, which can be applied to computers, mobile phones, voice recorders and other professional tools.

restore

　　　　In fact, the configuration of this mobile phone is also the mainstream flagship configuration: Xing uses a 2K resolution AMOLED screen, equipped with Qualcomm Snapdragon 820 quad-core processor, and built-in 4GB/6GB large memory +64GB/128GB storage space combination. It has a front camera with 8 megapixels+a rear camera with 20 megapixels.

Clean and powerful voice control　

　　　　For Meizu, there is no need to say too much about sound, because the audio is indeed a very experienced manufacturer, and Meizu Music Card is a classic product, which is very good in terms of workmanship and sound. For the flagship, Meizu is also very attentive to the sound quality, first of all, it is the exploration and application of sound quality chips: the CS43L36 decoding and amp integrated chip of CirrusLogic.

　　　Meizu adopts a CS43L36 decoding and amp integrated chip of CirrusLogic, which basically controls the audio parts involved.

Simple chip introduction (picture from CirrusLogic official website)

　　　　This chip is an integrated chip of decoding and amp that CirrusLogic specifically solves for mobile solutions. There is very little introduction on the official website, so we can only take the sense of hearing as a reference. Is the sound of the independent chip better or the integrated solution better?

Meizu official website Sound Quality Introduction Interface (Image from Meizu official website)

　　　　In terms of configuration, it is also the flagship level: Meizu uses a 5.2-inch 1080p screen with 2.5D cambered Corning Gorilla glass protection, and is equipped with MediaTek’s ten-core Helio X25. The processor adopts a 3-cluster architecture, based on ARM big.LITTLE, with a 20-nanometer process, and the highest frequency is 2.5GHz. Built-in memory combination of 4GB RAM+32GB/64GB ROM can smoothly run Flyme 5.6 based on Android 6.0 system, and has a built-in 2560mAh battery.

MEIZU

　Editor’s comment:

　　　　This mobile phone is very good with portable big ears, especially headphones with low impedance and low sensitivity. It can also be seen from the side that the thrust of this mobile phone is appropriate, even if the vocal performance is not exciting, it is a kind of voice that is a little warm and a little hoarse.

Excellent hammer l without mentioning sound quality　

　　　　I believe many friends are very interested in this year’s release. After all, this one can be said to be the main stream of the hammer mobile phone, especially the hammer and L. Especially from the configuration point of view, it is indeed the flagship mainstream level. In fact, the author is most concerned about the audio chip of the hammer mobile phone. As can be seen from the official website, this mobile phone uses chips that are very mainstream in the market and have excellent performance and parameters.

Parameter comparison between Smartisan and Smartisan L (quoted from the official website of Hammer)

　　　　CS4398 is the flagship decoding chip of Cirrus Logic, and its performance is excellent. It can also be found in the CD player with a price of more than 70,000 yuan. CS4398 is a decoding chip with a specification of 24Bit/192K Hz. It has a signal-to-noise ratio of more than 120 dB and a dynamic range, and the total harmonic distortion+noise is as low as 0.0005%. It adopts an advanced special multi-bit Delta-Sigma modulator and integrates mismatch noise shaping technology. (It seems to be very powerful) Although the price and index of cs4398 are not the highest and most expensive category of decoding chips, the sound of this sound quality chip is actually very special.

Smartisan series

Editor’s comment:

　　　　Although the specific parameters of this mobile phone were not put forward in detail at the press conference, it is very good in both the audio parameters and the actual listening sense. The single DAC chip not only improves the sound thickness, resolution, sound field and thrust compared with the mobile phone without a single DAC chip.

　See also ES9018K2M chip.　

　　　　This chip can be said that the author likes a chip very much. From the traditional computer to the terminal, almost all audio-related devices adopt ESS Technology’s chip technology, such as the recently popular Daao II HE1 and HiFiMAN 901 series, etc., and the chip technology of ESS Technology was adopted as early as possible, which is enough to show the importance attached by vivo mobile phones to audio.

The second generation of Daao uses the full version of ES9018 chip (quoted from Google).

　　　　Actually, for ESS, ESS Technology Inc. was founded in California in 1984, and its founders applied the scientific and technological inventions of audio reconstruction to electronic audio books and greeting cards. ESS then applied this audio technology to personal computers, successfully developed the first stereo single chip, and condensed the huge computer sound blaster card into a semiconductor chip, becoming the leader of audio chip technology for personal computers and notebook computers.

The mobile terminal adopts ES9018K2M chip (quoted from baike).

　　　　Today, ESS Technology Company has developed into an important manufacturer of semiconductor chips for multimedia, personal computers, consumer electronics and other products in the world. Besides computer audio chips, video technology (MPEG) and fax/Modem technology (Modem) of ESS provide customers with high-performance, advanced technology and reasonable price chips and supporting software solutions, which is one of the important pillars of ESS Company’s success.

　Plus

　　　　As a mobile version of ES9018, ES9018k2m perfectly solves the problem of huge power consumption, and has a dynamic range of 127dB DNR. The ESS audio chip has 127 dB, which can better show the details of music. The ultra-low distortion of -120dB THD+N can better restore the essence of music; The sampling rate reaches 192kHz/24bit, which will meet the performance level of the most demanding audio lovers. At the same time, it also supports a variety of lossless music such as DSD, APE and FLAC, so that you can enjoy higher quality music.

Editor’s comment:

　　　　This chip is mature, and it is very suitable to be placed on vivo X9 Plus. First of all, the sound is clean and the background is very black. At the same time, matching headphones can be described as "tiger balm", especially earplugs, which can get a good sense of hearing.

It has always been a custom chip.　

　　　　The biggest difference is the removal of the 3.5mm headphone jack. In fact, we still need to start from the initial disassembly. First of all, the author can find from the disassembly diagram that the previous 3.5mm headphone jack has been occupied by the TAPTIC Enging module and the home button. This module can bring a similar feel to the mechanical Home button when pressing the iPhone7. However, the impression of thinning the thickness of the fuselage did not appear, and I can only say that I was slightly disappointed.

From the disassembly diagram, we can see that TAPTIC ENGING in the new iPhone7 series occupies the position of 3.5mm headphones.

　　　　Red: apple/cirrus logic 338s00105audiocodec orange: Cirrus Logic 338S00220 audio decoding chip (x2).

　　　　1MORE’s three-cell ring iron earphone Lightning digital version with iPhone7 simple listening introduction:

　　　　This earphone had the first generation, 1MORE three-cell ring iron earphone. This time, the plug was replaced by Lightning and the decoding chip was built in. What about it? First of all, the biggest feeling for the author is: the improvement of overall analytical power and clean background. The song "Never say never" can fully show the characteristics of this earphone: the vocal performance is clear, and Justin Bieber’s voice line is clear and elastic, and the vocal knot is not particularly front, and there is no common sense of "sticking to the face". The low frequency shows that the dive is fast, the rebound is appropriate, and the amount is medium, so you won’t feel the boom. The resolution of high frequency on iPhone7 is still good, and there is no "harsh" feeling, while the extension performance is excellent.

1MORE’s three-cell ring iron earphone Lightning digital versionWith iPhone7

Editor’s comment:

　　　　I didn’t feel any trouble with this headset, because the iPhone7 came with a patch cord, so the 3.5mm headset can be used as usual. At the same time, the AirPods headset has been released recently, which can be said to be seamless, and there is no need to consider the fetters of wires at all. However, it is a little difficult to grab this headset, and it will take nearly 6 months to deliver it. It is better to replace the headset with the Lightning digital version interface, such as the 3-cell iron headset of 1MORE, which was simply evaluated above.

Traditional manufacturers play HiFi, and the sound is not bad. Cool 1S

　　　　This model not only has excellent performance, but also has remarkable accessories, especially headphones. For example, it is equipped with AKG custom headphones (the author studied it, and this headset is AKG high-end HiFi headphones).

Better resolution and clearer sound quality (quoted from Cool official website)

　　　　This audition experience can be said to be very good, not only the interface is very friendly, but also the operation can be very simple. At the same time, it also integrates a very good concert ticket purchasing function, so that you can enjoy the charm of music at the same time. It can be said that Cool 1S has truly achieved HiFi-level sound quality in terms of sound, not only with the built-in Harman Clari-FI sound source restoration algorithm, but also with the LiveStage virtual surround sound effect algorithm, so that the sound quality can be perfectly restored from the details to the sound field.

Editor’s comment:

　　　　The configuration of this mobile phone is also good: S1 adopts Qualcomm Snapdragon 821, screen, IMX298 sensor, equipped with rear camera and 0.1 second speed PDAF phase focusing technology; The 8-megapixel front camera can achieve a super-large pixel size of 1.4 μ m. Equipped with a large battery capacity of 4070mAh and AKG custom headphones, it can be said that it is an all-round mobile phone for HiFi to listen to music and play games.

　The first ES9038 high-quality chip.　

　　　　Supporting DSD in hardware decoding is simply a bunker, and vivo is the first audio chip of ES9038, which I am very concerned about. Furthermore, supporting hardware decoding will further improve the sound quality, and at the same time, three OPA1622 can provide a good thrust, so it is no problem to carry big ears.

　　　　Friends who used to watch the author’s evaluation before will be very curious. Why not evaluate the mobile phone sound? No, I’m trying vivo Xpay6 these days. The sound quality of this mobile phone still needs to be explained, because this mobile phone uses ES9038 chip, and this author can only find the data of ES9038 PRO:

Unfortunately, ES9038PRO will not appear on mobile phones (quoted from ESS official website).

　　　　ES9038PRO is a DAC chip with the highest index in the industry, with signal-to-noise ratio as high as 140dB and total harmonic distortion plus noise of -122dB. At the same time, it is a 32-Bit, 8-channel DAC. From the parameter point of view, ES9038PRO is enough to kill all opponents in the market, and it also successfully took over from the flagship ES9018S(129dB, -120dB) of the previous generation.

　　　　But the mobile phone is not available.

　　　　So the author went to the official website of vivo to find out and saw the introduction on the official website of vivo:

DSD hardware decoding is the highlight (quoted from vivo official website)

　　　　It can be found that in addition to starting ES9038, there are three operational amplifiers OPA1622. In fact, the most important thing is to support DSD hardware decoding. When you see DSD, someone may ask what format it is. In fact, this evaluation is mainly about lossless sound quality: nothing more than WAV and format, but the DSD format file is actually fundamentally different from WAV and FLAC. I won’t explain here such very profound words as WAV encapsulated in pulse code modulation format, DSD using pulse density modulation (PDM) and so on. But the author also briefly summarized it.

DSD format is still very advantageous.

Advantages:

　　　　1. Compared with WAV and FLAC formats, WAV has a higher sampling rate. Generally, WAV has a sampling rate of 44.1KHZ, while DSD can reach 176KHZ if converted into PCM format because it is a single bit stream.

　　　　2. The noise above the sound will be much cleaner. This has a great relationship with the role of the modem, which directly concentrates the noise on the UHF part.

Summary:　

　　　　These mobile phones really let you see the mainstream music HiFi mobile phones in 2016. Whether you want to listen to songs with a good sound quality mobile phone or an audio enthusiast, these HiFi music mobile phones introduced by the author here are all models that can represent the mobile phone market in 2016. This is equivalent to a review, or please be calm and wait for the author."2016 mainstream music mobile phone inventory test and listening"In this article, the author will use the sound card to install RAMM for testing, and then combine the corresponding sense of hearing.

　　　　Which music HiFi phone do you like and what you want to communicate with the author? Please leave a message below.

　　Put on a costume, and experience another life in a "crossing" way under the guidance of plots and clues … Nowadays, with its unique social participation and immersive experience, script entertainment is becoming the "new favorite" of young people’s leisure and entertainment.

　　The 2023 Henan Cultural Tourism and Creative Development Conference proposed to enrich the business experience and vigorously develop new cultural tourism. Nowadays, in Luoyang, script entertainment not only continues to innovate and develop in content and form, but also continuously integrates with scenic spots, museums, etc., creating a new format of immersive cultural tourism with local characteristics and boosting the development of new cultural tourism industry.

　　Creative guidance promotes the transformation from sightseeing to immersive experience

　　"Crossing" to the prosperous Sui and Tang Dynasties, experiencing the scenes of "literary test", "martial test" and "flying flowers" in the Sui and Tang Dynasties, and exploring the case together with "Di Renjie" and "Shangguan Waner" … Recently, the ancient city of Luoyi launched a brand-new live script entertainment product, allowing visitors to experience the immersive "crossing" journey of "dreaming back to the Sui and Tang Dynasties".

　　From "seeing the scenery" to "entering the scenery", "watching" to "experiencing". Guided by creativity, our city has made innovations in content and gameplay, promoted the cross-border integration of scripted entertainment with scenic spots and museums, "collided" traditional culture with novel creativity, and promoted the fashion expression of traditional culture and the modern transformation of heavy culture.

　　During this year’s Peony Culture Festival, Luoyang City held "Museum Fantastic Night" activities in Erlitou Xiadu Ruins Museum, Luoyang Museum, Luoyang Tomb Museum and Sui and Tang Grand Canal Culture Museum, which not only innovated the play of script entertainment, attracted tourists, but also spread Luoyang’s history and culture and improved Luoyang’s popularity and reputation.

　　The relevant person in charge of the Municipal Bureau of Culture and Tourism said that the city will also focus on the development model of "script entertainment+cultural tourism", and strive to create new diversified immersive cultural tourism formats such as "script entertainment+festival activities", "script entertainment+stage play" and "script entertainment+homestay" to expand the development space of script entertainment.

　　Developing the whole industrial chain economy of script entertainment by introducing education at the same time

　　Recently, in Luoyang Script Entertainment Industrial Park located in Luolong District, a new script internal testing activity is going on, and many employees in the script entertainment industry are sitting around the "trial version" to test and upgrade the new script to be promoted online.

　　Focusing on building China into the capital of script entertainment, our city has built the first script entertainment industrial park in China, attracting many well-known script entertainment enterprises such as Luoyang Kaka Media Culture Co., Ltd. and Luoyang FB Media Co., Ltd. to settle in.

　　As one of the early script entertainment enterprises in China, Luoyang Kaka Media Culture Co., Ltd. has developed into a head enterprise in the script entertainment industry, which integrates script creation and distribution, script entertainment host training and other businesses. "Enterprises will base themselves on their own advantages and boost the development of Luoyang script entertainment industry." Yang Kan, the person in charge of the enterprise, said that around Luoyang’s rich historical and cultural resources, more scene-based and immersive script entertainment projects will be laid out, and the interactive and entertaining features of script entertainment will be used to empower urban cultural tourism and further enhance the influence of Luoyang’s cultural tourism.

　　“LuoyangThe city will focus on the construction of the headquarters economy, encourage market players to become better and stronger, and make the script entertainment industry bigger and stronger. The relevant person in charge of the Municipal Bureau of Culture, Broadcasting and Tourism said that Luoyang Script Entertainment Industrial Park will focus on strengthening the key links of the script entertainment industry chain, such as script creation and distribution, DM training, operation background management and small program development, attracting supporting digital technology enterprises such as service road, sound and light, VR and AR, and vigorously developing the whole industry chain economy of script entertainment.

　　Enrich the format and speed up the construction of China’s "capital of script entertainment"

　　In September 2022,LuoyangAs the first special policy aimed at the script entertainment industry in China, the implementation plan for accelerating the development of the script entertainment industry in Luoyang was issued by the city. The plan proposes to implement four key tasks and related preferential policies, such as expanding the main body, cultivating the industrial chain, introducing talents and standardizing guidance, and strive to build China into the "capital of script entertainment".

　　Only when there is a high-quality script can there be a high-quality script entertainment format. Since 2022,LuoyangThe city has held two consecutive national script industry exchange meetings, encouraging outstanding creators in the domestic script entertainment industry to create scripts based on Luoyang’s rich history and culture, tell the story of Luoyang well and spread Luoyang’s good voice.

　　The relevant person in charge of the Municipal Wenguang Tourism Bureau said that,LuoyangThe city will accelerate the development of the headquarters economy of the script entertainment industry, formulate supporting policies from the aspects of brand creation, script incubation, industry training, talent introduction and industry management, etc., so as to attract more head enterprises and young talents to gather in Luoyang, continuously enrich the format of script entertainment, and accelerate the construction of China as the "capital of script entertainment".

As expected in the market, the new energy subsidy policy was officially released in 2019. Different from the previous 20% rebate standard, the subsidy standard in 2019 will be reduced by 50% on average on the basis of 2018.

The introduction date of the subsidy scheme for new energy vehicles can be said to be later than one year. The 2017 plan was introduced on December 30, 2016, the 2018 plan was introduced on February 13, 2018, and the 2019 plan has reached March 26, 2019. "yet we called and urged a thousand times before she started toward us, still hiding half her face from us behind her guitar" is really appropriate to describe the new energy subsidy policy in 2019.

Since the wind of the sharp decline in subsidies for new energy vehicles in 2019 has been blowing for several times, different programs have been passed from the end of 2018 to March 2019, and the industry has long had psychological expectations for the programs launched by the central government. Although this plan is very strong, it is all expected, even better than expected.

This time highlights several key points:

Subsidized standard passenger cars fell by 47-60%, and plug-in passenger cars fell by 55%; New energy buses dropped by 49-56%, and new energy special vehicles dropped by 45-80%. Cancel land compensation and subsidize infrastructure such as charging piles/hydrogen refueling stations instead.

The overall adjustment is very strong, which has great cost pressure for enterprises. The product lines of some enterprises will be greatly adjusted, and Ferrous lithium phosphate may make a comeback due to its cost advantage.

Despite the cancellation of land compensation, the subsidy policy for new energy buses will be introduced separately, and the determination of urban electrification will not be reduced.

Since electric vehicles have met the market conditions, the focus of policy support has shifted to fuel cell vehicles. Fuel cell vehicle subsidies will be refined according to different technical standards, and fuel cell subsidy policies will be introduced separately.

In the book, the extended range is classified as pure electric, and some experts have also mentioned supporting extended range vehicles after plug-in development to a certain extent. However, in this subsidy policy, the extended program subsidy is still classified as plug-in, and the prospect is worrying.

The payment method of subsidies was adjusted, and the punishment mechanism for safety accidents was put forward.

The following is a detailed interpretation of several key points of this subsidy policy.

One,Central subsidy adjustment

The maximum subsidy for all types of vehicles has decreased significantly, and the endurance and energy density have changed from "encouraging high endurance/high energy density" to "punishing low endurance/low energy density", and at the same time, the minimum energy density threshold has been raised.

(1) New energy passenger cars

The subsidy for passenger cars has changed to two grades, with pure electric slope retreat of about 47%-60% and plug-in slope retreat of 55%.

The threshold of energy density has increased from 105Wh/kg to 125Wh/kg, which requires continuous improvement, and the subsidy multiple has been lowered.

The minimum is raised from 150 kilometers to 250 kilometers, and the standard of energy consumption subsidy multiple is adjusted, which obviously improves the requirements for overall energy saving.

By canceling the subsidy below 250 kilometers, the subsidy multiple of low energy density will be reduced, and enterprises will be encouraged to produce cars with high energy density and high endurance. Combined with the industrial policy of low-speed electric vehicles, low-speed electric vehicles may be responsible for the shorter range below 250 kilometers, and it is difficult for A0 and A00 electric vehicles to compete with low-speed electric vehicles in cost.

Due to the decrease of subsidies and the increase of energy density in Ferrous lithium phosphate, the cost of Ferrous lithium phosphate shows certain advantages, and some enterprises may switch from Sanyuan to Ferrous lithium phosphate in low endurance vehicles.

Some enterprises with relatively backward technology or lack of industrial experience will be under great cost pressure, thus being forced to raise the price of automobile products, reducing the market competitiveness. At present, new car-making forces such as Tucki and others have raised the price of their products.

The leading enterprises have abundant funds and leading technical strength, and have full expectations for subsidies. They will continue to promote the development of vehicles with high cruising range, reduce costs by optimizing design and production, and continuously improve market competitiveness. Therefore, the impact on leading enterprises is not so great, and the mainstream A-class and above vehicles are less affected. The selling prices of Geometry A and Aions newly introduced by Guangzhou Automobile Co., Ltd. and Guangzhou Automobile Co., Ltd. did not reflect the obvious influence of subsidies, while Weimar and Guangzhou Automobile Co., Ltd. introduced the strategy of price protection.

The most important thing is to reduce the amount of subsidies, promote the marketization of new energy vehicles, eliminate the fittest for enterprises, and concentrate the automobile production capacity on advantageous areas and enterprises.

(2) New energy buses

The gradient is 49%-56%, and the minimum energy density is required to rise from 115Wh/kg to 135Wh/kg.

The energy efficiency and subsidy coefficient were adjusted, and the requirement was increased by 5 percentage points.

New energy buses may be rushed to install during the transition period.

(3) The new energy trucks have been adjusted in detail.

By simply subsidizing the battery capacity, the weight classification is increased. The maximum subsidy is reduced from 100,000 yuan according to different types, and the reduction range ranges from 45% to 80%.

At the same time, the minimum energy density is increased from 115Wh/kg to 125Wh/kg, and the subsidy coefficient is adjusted.

There are two points worthy of special attention in terms of new energy trucks.

1) The subsidy category of "special purpose vehicle" was cancelled, and the classification of total quality of freight cars was increased.

This means that the market develops from logistics vehicles to larger trucks, and even pure electric heavy trucks appear; The subsidy policy for new energy special vehicles was cancelled.

2) The subsidy category for trucks has been added.

Increase market choices, and trucks with a total mass of more than 12 tons can choose the technical direction of plug-in hybrid to adapt to more market changes.

Second, cancel local subsidies and promote fair market development

This is a continuation of the spirit conveyed in the Regulations on Investment Management of Automobile Industry and the Implementation Plan for Further Optimizing Supply, Promoting Steady Growth of Consumption and Forming a Strong Domestic Market (2019), breaking local protection, promoting market-oriented development and creating a level playing field.

At the same time, we will continue to improve the market consumption environment by subsidizing infrastructure construction, and support the development of new energy vehicles through indirect financial subsidies. However, hydrogen refueling station enterprises get development opportunities and can focus on related enterprises.

Despite the cancellation of land compensation, new energy buses will be introduced by a separate subsidy policy, showing the importance attached to urban electrification.

Third, fuel cell vehicles are listed separately, and the degree of attention is unprecedented

Fuel cell vehicles are in a critical period of technological development and market introduction. In the past, the subsidy policy for fuel cells was too simple, which only stipulated the minimum rated power and the minimum cruising range, which also led to the design of the subsidy line for automobile products in the announcement catalogue, all of which were 30KW.

The fuel cell subsidy policy was postponed, presumably in order to refine the subsidy policy and avoid the previous design of fuel cell vehicles under the pressure of subsidy line and the road of pursuing high energy density and ignoring safety like electric vehicles again.

Fourth,Extended-range electric cannot be classified as pure electric.

The extended subsidy policy is still classified as plug-in hybrid. The Investment Regulation of Automobile Industry classifies the investment projects of extended-range electric vehicles as pure electric vehicles, which is considered by many people in the industry as a signal of the rise of extended-range electric vehicles, because the advantages of extended-range electric vehicles can only be reflected when compared with pure electric vehicles, but the competitiveness is weak when compared with plug-in hybrid vehicles.

The subsidy policy for the extended range cannot be classified into pure electric vehicles, so the development prospect of the extended range is worrying, and the "ideal" of the extended range may be "cool".

Five,Emphasize supervision and safety.

Supervision is divided into two aspects: authenticity and security.

Authenticity is achieved by monitoring the operating mileage and adjusting the settlement method. Starting from 2019, for vehicles with operating mileage requirements, a part of subsidy funds will be paid in advance after the sales are registered, and the vehicle enterprises will apply for subsidy liquidation after meeting the operating mileage requirements. If the operation does not meet 20,000 kilometers within 2 years from the date of registration, no subsidy will be granted, and the pre-allocated funds will be deducted at the time of liquidation. This gives enterprises more abundant liquidity and more flexibility to cope with market changes.

Safety emphasizes the consistency of safety accident prevention and product production. The competent authorities of the industry will speed up the establishment of a normal mechanism for product safety monitoring and "consistency" sampling inspection. Suspension or cancellation of vehicles with major safety accidents caused by product quality or with major quality defects identified by relevant departments, and corresponding suspension or cancellation of financial subsidies.

Hydrogen Cloud Chain believes that with the rapid expansion of China’s new energy automobile industry, low-end enterprises that rely on subsidies to survive are doomed to be eliminated, and infants who are breastfeeding will eventually be "weaned". How to ensure quality is the key to "survival".

　　Recommended reading:Summary of free live classes for primary and secondary school students throughout the country during the epidemic (schedule+lecture entrance)

Affected by the COVID-19 epidemic, colleges and universities all over the country started online teaching on the original starting date (around February 17th). As of March 14th, online teaching in most colleges and universities has been going on for about four weeks, and the online teaching has entered a relatively stable state. At this time, it is urgent to investigate and study the effect of online teaching in colleges and universities nationwide, so as to provide reference for college teachers to improve the effect of online teaching. Therefore, the research group of Hebei University conducted a survey on the effect of online teaching during the epidemic period for college students nationwide from March 14th to March 17th, 2020.

A total of 5094 valid samples were obtained in this survey. The respondents came from 113 universities in China, covering 13 disciplines, from the first year of university to the third year of graduate students, of which 34.9% were men and 65.1% were women.

According to the survey data, 69.16% of the students spend more than 4 hours in online teaching every day, among which 21.83% have more than 6 hours in online courses every day, and only 30.84% have less than 4 hours in online courses every day. It can be seen that the online learning task of college students is heavier.

First, the overall evaluation of online teaching-"It is not easy to say that I love you!"

Then, compared with the traditional classroom, what is the overall evaluation of students on the simple online teaching?

　Figure 1 Percentage of overall evaluation of online teaching (unit:%)

1. Network teaching has no obvious effect on highlighting students’ dominant position.

Compared with traditional classroom teaching, online teaching highlights students’ dominant position. Do you agree with this statement? In the answer to this question, 45.23% of the students said "agree or strongly agree", 41.58% said "average" and 13.19% said "disagree or strongly disagree".

2. Online teaching has improved students’ self-study ability.

Compared with traditional classroom teaching, online learning has enhanced my self-study ability. Do you agree with this statement? According to the statistics of the answer to this question, 59.71% of the students chose "agree or strongly agree".

3. Web-based teaching has not well mobilized the enthusiasm of college students for class participation.

Compared with traditional classroom teaching, students are more enthusiastic about participating in online classroom. Do you agree with this statement? According to the statistics of the answer to this question, only 38.10% of college students said "agree or strongly agree" and as many as 22.58% said "disagree or strongly disagree".

4. The effect of online teaching in improving the interaction between teachers and students is average.

Compared with traditional classroom teaching, there is more interaction between teachers and students in online teaching. Do you agree with this statement? According to the statistics of the answer to this question, only 34.58% of college students said "agree or strongly agree" and as many as 19.55% said "disagree or strongly disagree".

5. The learning efficiency of students in online classroom teaching mode is not as good as that in traditional classroom.

Compared with traditional classroom teaching, online learning improves learning efficiency. Do you agree with this statement? According to the survey of this issue, as many as 29.78% of the students said "disagree or disagree very much", and only 29.78% said "agree or disagree very much".

Second, the choice of teaching methods after the epidemic-"still reluctant to part with you!"

Fig. 2 The situation of students’ choice of teaching methods after the epidemic.

The data shows that the teaching method of "traditional classroom teaching is the main method, supplemented by network teaching" has become the first choice for college students after the epidemic. This shows that the position of traditional classroom teaching cannot be replaced, but simple traditional classroom teaching and simple network teaching are not the first choice of students. On the contrary, the teaching method of "traditional classroom teaching is the main one, supplemented by network teaching" has become the first choice of college students. This requires that colleges and universities in China should seize the opportunity of implementing large-scale network teaching brought by the epidemic and vigorously develop network teaching in conjunction with traditional classroom teaching methods in the reform of teaching methods after the epidemic.

Third, the evaluation and analysis of the teaching effect of specific courses-"Old wine in new bottles, both are important"

We ask students to choose the specific course that they think is the best or the worst this semester to evaluate and answer the specific situation of this course.

1. Students have a high evaluation of the selected courses.

Among the scores of the selected courses, 74.07% students scored above 80, 18.59% students scored 60-80, and only 7.34% students scored below 60. It can be seen that students have a high evaluation of the effect of the selected courses.

Table 1 Distribution of College Students’ Evaluation of Specific Courses

2. The teaching effect of specialized courses is better than that of public courses, the teaching effect is better in the morning, and the network teaching effect of small-scale classes is better.

Table 2 Percentage of grading categories with different course nature, class time and class size (unit:%)

The results of data analysis show that there are significant differences in the teaching effect of different courses, different class periods and different class sizes. The teaching effect of specialized courses is better than that of public courses, the teaching effect of morning classes is better, and the network teaching effect of small-scale classes is better.

3. The teaching effect of live video is obviously better than other methods.

Table 3 Percentage distribution of teaching effect scoring categories by teaching form (unit:%)

The data shows that the teaching effect of live video is better than other forms, which also shows that "seeing is believing". Although students study at home, they are still eager for "face-to-face" real-time classroom form.

4. Courses with better image and sound transmission effect have better teaching effect.

Table 4 Percentage of course scores with different image effects and sound effects (unit:%)

The biggest feature of network teaching is that it is subject to the network transmission situation. The results in Table 4 show that different network conditions and sound transmission effects will bring different teaching effects, and the evaluation of teaching effects with good network conditions and sound transmission conditions is also better.

5. Electronic textbooks and supplementary materials are provided, and the teaching effect is better.

Table 5 The provision of all kinds of course resources and the scoring group of course teaching effect

During the epidemic period, students can’t go to school to get paper-based course materials such as textbooks and teaching AIDS, so whether online courses provide rich electronic course resources has become one of the factors that affect the teaching effect.

6. Online check-in and preview tasks are arranged in advance, and the online teaching effect is better.

Table 6 Pre-class process and course teaching effect score grouping

The results in Table 6 show that the pre-class task arrangement and electronic sign-in of online courses are also factors that affect the teaching effect of the course.

7. The course of using electronic blackboard books has a good teaching effect.

Table 7 Percentage distribution of teaching effect scoring categories by whether there are electronic blackboard books (unit:%)

Although the fluency and effect of online teaching electronic blackboard can’t be compared with the physical blackboard, the data show that the teaching effect of the course using electronic blackboard in the course is obviously better.

8. The higher the number of teacher-student interactions and the number of students who speak, the better the classroom effect.　

Table 8 Teaching effect evaluation groups of courses with different times of teacher-student interaction and number of students who speak (unit:%)

Classroom interaction is an important link and means to improve students’ participation and enthusiasm in class, which is also fully applicable to online teaching.

9. The course of homework and answering questions in time after class is arranged, and the teaching effect is good.

Table 9 After-class links and teaching effects

Paying attention to after-class links can effectively improve the teaching effect of the course, which is also fully applicable to online teaching.

10. Courses that can be played back have better teaching effect.

Table 10 Percentage distribution of teaching effect scoring categories by whether courses can be replayed (unit:%)

Online courses can be recorded and replayed conditionally, and the teaching effect of courses with replay is better, which requires teachers to make full use of the advantages and specialties of online teaching.

To sum up, the factors that affect the teaching effect of online courses are not only the traditional teaching factors such as preparation of teaching resources before class, interaction in class, homework and counseling and answering questions after class, but also the specific class form and the transmission effect of images and sounds. That is to say, online teaching only changes the teaching way and carrier, and its connotation has not changed except choosing the appropriate class form and smooth network guarantee, which depends on the energy input of teachers in the teaching of this course. It is called "new bottles and old bottles"

Thanks: The epidemic is dissipating, and spring is just around the corner. Thanks to the students from all corners of the country, and thank you for your sincere answers. Once again, I wish every one of you.
