　　　　　　　 Movie Network News(Photo/Yang Liu, Text/Xie Yawei) In September 2009, He Ping’s 6-year-old work "Wheat Field" was released. In this mixed film, the heroine Fan Bingbing undoubtedly became the focus of the whole film. Perhaps no one noticed that there was a maid Yaner who had been following her around next to the mayor’s wife. In [Movie Network]’s recently concluded "Search for the next movie coordinate – the hottest newcomer show in 2009" prize voting activity, a girl named Wang Jiajia ranked second among the 13 candidate artists, she is the role of Yaner, the little-known graduate student of the directing department of Beiying Film, who surprised everyone and became the hottest newcomer in the movie industry in 2009 with high popularity. On March 2, Wang Jiajia accepted an exclusive interview with [Movie Network] after recording the "Light and Shadow Star Podcast" program.

Good student who doesn’t like to talk: I finished talking for a week

　　　　　　　 Perhaps it was because she was still studying at school that Wang Jiajia was full of student spirit. The girl in front of her was tall and slender, with white and delicate skin, gray knitted sweater, blue jeans, and a pair of ordinary espadrilles. She came to the recording scene refreshingly. Maybe she is the least star-like artist that "Light and Shadow Star Podcast" has welcomed. Wang Jiajia doesn’t like to talk, and even if she talks to you, she will whisper softly. Such a quiet girl has to record large sections of oral speech, no wonder she will say, "I finished talking for a week today."

　　　　　　　 Wang Jiajia graduated from the ballet department of the Beijing Dance Academy and is now a graduate student in the directing department of the Beijing Film Academy. The host industry is naturally unfamiliar to her. At the beginning of the recording, Wang Jiajia was a little nervous and acted very stiff, and the director kept calling her to stop and ask her to do it again. In front of the camera, Wang Jiajia is like a primary school student, listening carefully to the director’s guidance, not speaking, but nodding. At this time, she does not seem to belong to this impulsive entertainment industry, but is just an ordinary girl next door. Wang Jiajia is very smart. After a little guidance from the director, the recording became more and more natural and smooth. However, because she wore contact lenses to read the subtitles for a long time, Wang Jiajia’s vision was blurred later, and the recording was very hard. When the director offered to let her take a break, she insisted on continuing filming, fearing that it would delay everyone’s time.

　　At 2:9 on June 25, our country successfully launched the 46th Beidou navigation satellite with the Long March 3B carrier rocket at the Xichang Satellite Launch Center.

　　The satellite is the 21st networking satellite of the Beidou-3 system and the second satellite in tilted geosynchronous orbit. After a series of in-orbit tests, the satellite will network with the 20 Beidou-3 satellites previously launched to provide timely services and further enhance the coverage and service performance of the Beidou system.

　　As a resounding calling card of our country’s independent innovation, China’s Beidou is deploying the "big chess game" of global navigation at a leading speed.

　　In the context of the deployment of constellations with single-orbit satellites by GPS in the United States, Glonass in Russia, and Galileo in Europe, Beidou from China is unique in using three kinds of orbiting satellites to form a hybrid navigation constellation, contributing Chinese wisdom and Chinese solutions to the international satellite navigation technology system. What are the mysteries of Beidou’s "chessboard"? The reporter walked into the five colleges of the Aerospace Science and Technology Group, known as the "base camp of Beidou", to find out.

　　Three types of "chess pieces" in China’s Beidou chess game

　　So far, Beidou-3 has successfully launched 21 satellites, including 18 MEO satellites (medium circular orbit satellites), which are called "Mengxing" by netizens because of their small and flexible English abbreviation; 1 GEO satellite (geostationary orbit satellite), which is called "Jixing" by Beidou people; and two IGSO satellites (tilted geostationary orbit satellites), which are called "Aixing" by Beidou people.

　　Like chess pieces on a criss-crossing chessboard, these three types of satellites hold their posts in different orbits –

　　"Moe Star" is the main force of the global network, running around the earth tirelessly, making its own under-star trajectory constantly draw wavy lines in order to cover a wider area of the world; "Ji Xing" always moves with the rotation of the earth, in order to always focus on the motherland; "Love Star" is like a hard-working bee, making its under-star trajectory always focus on the Asia-Pacific region and dance the figure of eight.

　　The 46th Beidou navigation satellite launched this time is the second "love star" of the Beidou-3 system.

　　These three types of "chess pieces" with outstanding achievements are not the first time they have joined forces in the Beidou No. 3 system. They have jointly displayed "Chinese kung fu" in the Beidou No. 2 system, but their respective job responsibilities have changed.

　　Based on the national conditions, not blindly seeking success

　　It is not difficult to see that to undertake the task of global networking, it is enough to have "Moe Star", why should "Love Star" and "Ji Xing" be pulled into the team?

　　To answer this question, we have to start with the debate about the direction and route at the beginning of Beidou.

　　What kind of path does China’s navigation satellite take? Is it a step-by-step step to global networking, or a small step and a phased leap? In the fierce collision of ideas, opinions gradually tend to favor the latter.

　　Academician Fan Benyao, chief designer of the Beidou-1 satellite, who participated in the discussion of the technical route, said: "It took a lot of time and money to build the system so large [global networking] at one time. At that time, the reform and opening up had just begun, and the users were concentrated in the domestic and surrounding areas of our country. Therefore, the technical approach of’regional first, global later ‘is very correct, in line with China’s national conditions and has Chinese characteristics."

　　China-Asia-Pacific-Global, the three-step route determines the pattern of Beidou. In the first two steps, Beidou needs to lock in China and the Asia-Pacific region to provide services, "Jixing" and "Aixing" obviously have more advantages, while "Moe Star" is not very economical, and many key technologies on "Moe Star" have not yet broken through. But we can’t completely give up "Moe Star", we must verify the technology through actual combat, after all, the final step is still to go global.

　　Therefore, for the first time, the Beidou people of the Five Academies have built the GEO/IGSO/MEO, that is, the hybrid constellation of "Jixing", "Aixing" and "Moe Xing", and built the Beidou-2 regional satellite navigation system that integrates basic navigation, location reporting and other services with the minimum number of satellites, becoming a model for the construction of regional satellite navigation systems in the world.

　　This kind of technical system can efficiently build a regional system and expand the global system at the same time. During the construction of the Beidou-2 system, a series of bottlenecks were gradually overcome through the launch and operation of four "Moe Stars" in orbit. Therefore, when Beidou started its global networking journey, the "Moe Star" who jumped into the main force was able to show its power.

　　However, at this time, the "auspicious star" and "love star" did not withdraw from the stage of history. The Beidou experts of the Five Academies told reporters that the Beidou constellation is a team, and the most emphasis is on complementary advantages and the overall best. The Beidou people fully considered the advantages of "auspicious star" and "love star", and designed a small number of positions for them, but their role is very critical. They not only undertake the "assist" responsibility of cooperating with "Moe Star" and significantly enhancing the overall technical indicators of Beidou No. 3, but also carry a lot of "artifacts" to expand and verify the road of Beidou in the future.

　　"This Beidou route and constellation design, which is full of the practical wisdom and pragmatism of the Chinese nation, has laid the most solid foundation for the country’s heavy weapons," the expert said.

　　Check the bottlenecks on the list one by one

　　In fact, if the intelligent plan design is not implemented in action, it is ultimately a blueprint. From design to completion, the most test of technical strength and perseverance. Since the Beidou No. 1 project was established in 1994, the Beidou people of the Five Courts have embarked on the long road of Beidou.

　　In order to build the world’s first hybrid constellation regional navigation satellite system, the Beidou-2 satellite system, the scientific research team from the Five Academies has broken through many key technologies such as hybrid navigation constellation design, high-stability signal broadcasting channel, active and passive positioning integration, and high-precision and high-stability thermal control of on-board atomic clocks. For the first time, three services of navigation and positioning, short message communication, and differential enhancement have been integrated. China’s Beidou has thus obtained (meaning the society – reporter’s note) a new skill-

　　"Jixing" and "Aixing" are a series of key technologies for high-precision navigation; the flexible and efficient spatial data management system of "Aixing" and "Mengxing" has improved the level of satellite information management and autonomous operation.

　　In the third step of entering the global network, China’s Beidou people have achieved the improvement and leap of our country’s navigation satellite capabilities: our country’s first full-truss satellite platform, bearing efficiency and other indicators have reached the international first-class level; for the first time, a unique new type of navigation signal broadcasting has been realized, which has greatly improved the user’s anti-jamming ability and ranging accuracy; breakthrough in multi-orbit hybrid constellation inter-satellite link technology to achieve "one-stop management" of navigation constellations; breakthrough in satellite independent health management technology, the number of unplanned interruptions of satellite signals has reached the international advanced navigation satellite service level.

　　As the bottlenecks on the list were ticked off one by one, China’s Beidou firmly grasped the core technology in its own hands and rushed out of Asia to the world.

　　One link is "twisted", one item after another is "broken".

　　On the Beidou Long March, the Chinese Beidou pioneered the management model of the aerospace project group, forming a new system exploration, key technology research, achievement transformation, talent training benign mechanism and complete scientific research supporting facilities, which strongly supported the batch production and intensive launch of Beidou satellites, and created the "China Speed" of constellation networking.

　　The shining constellation was created by China and will serve the world.

Physical appearance is very important for a person, but temperament is also very important. Even if the appearance is ordinary, the figure is average, but the temperament is outstanding, it can stand out among ordinary people.

For girls with ordinary figure and average appearance, it will be a way to upgrade their beauty by improving their temperament, and it will be easier to achieve. So let’s introduce how to improve temperament and how to become a temperament beauty.

First, accessories are very important, embellishing fashion

Matching is not only the "matching" of clothing, but also the "matching" of accessories, which are the finishing touch, but also a good helper to enhance temperament.

For example, the straw hat, a single product with common materials and styles, can be a sense of atmosphere because of the exquisite collocation of accessories.

In the collocation of many dresses and atmosphere, straw hats provide a temperament improvement and a sense of exquisiteness. At the same time, there are some exquisite accessories, which can also be a plus item for exquisiteness.

How can an ordinary T-shirt wear a different feeling from others? In fact, the main reason lies in accessories.

Therefore, if you want to stand out in daily life, increase the sense of exquisiteness and temperament, then accessories are a very important item.

As big as shoes and bags, as small as earrings and bracelets, it is the theme of exquisite temperament collocation, so if you think the collocation is too common, then it is better to try to start with accessories, which is simple and easy to learn, without wasting money, and the student party can easily own it.

Second, it is very important to cover up when you are out of the street.

Many times you don’t really need to show your face, such as going to the library, going to the supermarket, going to the park and so on. Especially on the university campus, you really don’t need to show your face.

So,Mask+hatThe collocation mode has been opened, and another plus item of fashion sense comes from it. In fact, we can find that wearing a mask and a hat is not a beauty, but can also pretend to be a beauty.

Because hats and masks cover most of our faces, we only need clothes to create an atmosphere. Especially in autumn and winter, there is no need to show skin color, so it is more suitable for "obscure"collocation scheme.

So at this time, as long as these two parts are covered, then we only need to work hard on clothing. Here we will focus on the version and learn to wear the style by taking advantage of the body.

For example, oversize wind is more suitable for bony salt girls, and it is more sensible to wear. For another example, fat mm is actually more suitable for a relatively slim dress, and it is really important to have a waistline.

Even we can choose a style that suits us according to a certain part of ourselves. For example, short legs can try Japanese girlish style, and short skirts are particularly high. For example, you can try French retro style with narrow shoulders, and there is always a style that suits you.

Third, color matching is very important to get rid of the feeling of passers-by

In fact, color is a very important factor affecting the senses. Clothes need to have "color" in addition to "shape". Choosing the right color can easily get rid of the feeling of passers-by.

For example, a simple black-and-white match, then we can make it interesting by contrasting colors, so that a simple and low-key match will look richer.

But the color is not forced to add, the simplest way to match is:Basic color+popular color.

The first kind, such as beige+red, the warm red collocation brings "passion" and gets rid of rigidity.

The second kind, such as black+green, the green of floral design is like a new bud in spring, lively and fresh, and literary fashion.

And these colors that we ignore are actually an important factor to enhance the sense of collocation fashion. And the sense of fashion is closely related to temperament, so the overall color coordination, then temperament will naturally improve a lot.

Therefore, when you appreciate some fashionable paintings and go shopping, you can pay attention to the matching colors that make your eyes shine, which may bring you a lot of happiness.

November 22 – 23, Shenzhen Futian District People’s Government, Shenzhen Futian District Science and Technology Innovation Bureau and the Guangdong-Hong Kong Macao Digate District Digital Economic Research Institute ("Idea") jointly organized the IDEA Conference. Director of the Idea Shouyuan, foreign academician of the US National Academy of Engineering, External Academician of the UK Royal Engineering, Double Professor Tsinghua University Double Professor Shen Yanyong released a number of prociation teams and Guangdong and Hong Kong, Macau Duwan District, Association A large-scale open medical knowledge map (Biomedical Informatics Ontology System, referred to as "BIOS").

Shenyang explains in the BIOS conference

Medical knowledge map is a special database consisting of biomedical concept name, concept classification, conceptual relationship, and corresponding ID system. It is used to support medical natural language processing, artificial intelligence modeling, and industry data exchange. It is medical data and One of the most important infrastructure in artificial intelligence is a strategic impact on industry development. The National Medical Library of the US National Health Center has developed and developed in 1986, the unified Medical Language System, referred to as "UMLS") is the most authoritative English medical knowledge map, which is the English national medical data technology and The development of the industry made an excellent contribution. For a long time, the lack of large-scale open medical knowledge maps in the Chinese field is one of the main constraints of my country’s medical big data and artificial intelligence industry.

Description of the number of entities and relationships included in the BIOS knowledge map

Medical naming entity identification demonstration based on BIOS knowledge map

In order to solve the lack of medical knowledge maps in the Chinese field, and further enhance the construction level of medical knowledge maps in the international scope, Yu Zun leads the team to conduct a five-year technical research, and has developed Chinese based on map segmentation and depth learning. Chinese Electronic medical records do not supervise multi-granular particless words and terminology extraction, knowledge determined by medical terms to quantization and regularization, high-throughput medical relationship, biomedical translation, etc. Cooperating with the Idea Research Institute in November 2020 to reach a cooperation. With the support of leading algorithms, powerful strength and oversized corpus data, only in just one year, the two teams started from the original underlying medical terminology, and established a new Chinese and English bilingual medical knowledge map with complete independent intellectual property rights. BIOS, its size is close to existing authoritative knowledge map UMLs, and forming a multi-point transcendence in content quality.

The BIOS is currently published (http://bios.idea.edu.cn). At the same time, adhering to the comprehensive improvement of the development of China’s medical big data and artificial intelligence industry, BIOS is in the near future to open full data downloads with CCBY-NC-ND protocol.

In the future, Tsinghua University Statistical Research Center will cooperate with the IDEA Research Institute and more domestic top hospitals, continuously expand the content of BIOS and improve their quality. This will not only make the basic improvement of medical high data and artificial intelligence industries, but also the radiation international and drive the global industry.
