CCTV News:Recently, the Ministry of Human Resources and Social Security issued the "Thirteenth Five-Year Plan for Technician Education" (hereinafter referred to as the "Plan"), which is the first five-year plan for mechanic education of the Ministry of Human Resources and Social Security. "Planning" for the first time made it clear that graduates of intermediate classes, advanced classes and preparatory technician (technician) classes in technical colleges should be treated according to the equivalent of secondary school, junior college and undergraduate education.

　　The annual training volume of technical schools in China is more than 5 million, but the number of middle and senior technicians is insufficient.

　　By the end of 2015, there were 2,545 technical colleges in China, including 434 technician colleges with 3.22 million students, and the employment rate reached 97.4%, and the employment rate of key colleges reached 100%. At the same time, actively carry out all kinds of vocational skills training for the society, with an annual training volume of more than 5 million people.

　　At present, the number of middle and senior technicians in China is insufficient, the gap is large, the overall structure of professional skilled personnel is not reasonable, and the distribution of high-skilled personnel in regions and industries is uneven, which makes some high-level and high-quality industrial designs only stay on perfect drawings. This not only restricts the development of individual enterprises, but also adversely affects the overall level of China’s manufacturing industry. More seriously, it even makes the rise of national industries lack a solid foundation.

　　The central government has repeatedly proposed to attach importance to the training of high-tech talents.

　　In March this year, Li Keqiang, Premier of the State Council of the People’s Republic of China clearly stated in the government work report that it is necessary to "encourage enterprises to carry out personalized customization and flexible production, cultivate the craftsmanship of Excellence, increase varieties, improve quality and create brands."

　　On December 8th, this year, Ma Kai, Vice Premier of the State Council, pointed out that high-skilled talents are an important part of China’s talent team, the core backbone and outstanding representative of the workers’ team, an important force to innovate technical skills and create social wealth, and play an important role in promoting technological innovation, economic development and social progress.

　　Ma Kai emphasized that to implement the innovation-driven development strategy, implement Made in China 2025, promote economic upgrading, efficiency improvement and upgrading, and move towards the middle and high-end level, we must speed up the training of a skilled talent team with sufficient quantity, excellent quality and reasonable structure.

　　By the end of the "Thirteenth Five-Year Plan", a modern mechanic education system will basically be formed.

　　The "Planning" clearly stated that by the end of the "Thirteenth Five-Year Plan", a modern mechanic education system will basically be formed, in which the scale of running a school is suitable for market demand, the professional structure is suitable for industrial development, the integration of schools and enterprises runs through the process of running a school, the teaching reform realizes the combination of work and study, the internship and training are closely linked with jobs, the level and scale of skilled personnel training are more matched with economic and social development, and the social service function is more perfect.

　　The Plan puts forward six development goals.

　　"Planning" briefly summarizes the development status, existing problems and the situation faced by the national technical education, clarifies the guiding ideology of technical education during the "Thirteenth Five-Year Plan" period, and emphasizes the fundamental requirements, development orientation, training core, school-running concept and development purpose. It puts forward the basic principles of overall planning, employment orientation, connotation development and cultivation of craftsman spirit, and six development goals of "more reasonable layout, more perfect functions, more standardized management, continuous improvement of quality, more distinctive features and more optimized environment".

　　The Plan puts forward corresponding measures for the six major goals.

　　① Coordinate the coordinated development of the eastern, central and western regions, optimize the structure of technical colleges, vigorously develop technical colleges, support the development of industrial enterprises and private colleges, and stabilize the scale of educational system.

　　CCTV News:On January 29th, the State Council Press Office held a press conference on the development of industrial communication industry in 2018. When answering a reporter’s question, Wen Ku, director of the Information and Communication Development Department of the Ministry of Industry and Information Technology, said that 5G will become the infrastructure for building a new generation information network of the Internet of Everything, and will work together with the global industry to jointly promote the maturity of 5G chips and terminals.

　　Reporter: What kind of city will get a temporary 5G license? 5G has completed the third phase of testing. What is the estimated investment in 5G in 2019?

　　Wen Ku: The Ministry of Industry and Information Technology attaches great importance to promoting the development of 5G, encourages enterprises to actively participate in the international standardization of 5G, and promotes the formation of a global unified 5G standard. In terms of R&D promotion, China has a 5G propulsion group, namely IMT-2020(5G) propulsion group. Under the organization of this promotion group, technology research and development experiments were carried out, which accelerated the technological maturity of relevant R&D enterprises in various countries; At the same time, China also has a major project, in which R&D enterprises including foreign enterprises are invited to jointly participate in the research and development of 5G, carry out technical experiments and strengthen overall cooperation in this respect.

　　In the early stage, the Ministry of Industry and Information Technology released the plan of 5G frequency in time, creating a good environment for 5G development. Last week, the IMT-2020 Promotion Group reported the entire 5G test in 2018 to the media. Judging from the test, the current system equipment products have basically reached the pre-commercial level; Chips and terminals, the terminals that can be seen at present are still large boxes of cabinet terminals, which are used for performance testing, but the real commercial terminals have not yet been seen. As far as we know, terminal chip and terminal research and development, chip companies and terminal companies are in full swing.

　　Judging from the current progress, it should be expected that there will be better commercial terminals in the middle of this year. Unlike 4G, 5G will become the infrastructure for building a new generation information network of the Internet of Everything, and there will be many applications in this respect. Among them, the Internet of Vehicles is one of the important areas of 5G applications. The accelerated development of the Internet of Vehicles has also accumulated experience for the exploration of cross-industry and cross-domain integrated applications of 5G, providing a better and broader platform for the development of 5G.

　　Next, we will further implement the spirit of the Central Economic Work Conference, continue to adhere to the concept of openness, cooperation and sharing, strengthen international cooperation, persist in opening to the outside world, and work together with the global industry to jointly promote the maturity of 5G chips and terminals, accelerate the construction process of 5G networks, increase the promotion of 5G applications, and strive to enable users to use 5G terminals as soon as possible and enjoy all kinds of 5G applications.

Xin Yang, Professor and Doctoral Supervisor, School of Electrical and Information Engineering, Hunan University.

Red Net News Reporter Liu Zhixiong Zhu Liping Intern Hu Xinghai Changsha Report

If the integrated circuit field represented by CPU is the "brain" of modern equipment, then the power semiconductor chip is the "heart" that provides power. After returning from Cambridge University, Xin Yang, a professor at the School of Electrical and Information Engineering of Hunan University, devoted himself to the research of power semiconductors. He wanted to build "China Core".

"Our country was 30 years behind in this respect and was stuck in the neck for too long." Xin Yang said with emotion.

Xin Yang’s concern about power semiconductors stems from a teacher’s words during his undergraduate period. "Power semiconductors are the core of electric energy conversion, and a generation of power semiconductor chips determines the performance of a generation of equipment." It also originated from Xin Yang’s "China Heart". Since childhood, parents have taught Xin Yang to be an indispensable talent for the country.

Previously, the research results of the subject with Xin Yang as the first author were published in a top international academic journal of physics. This achievement provides a new idea for solving the serious oscillation problem of new power semiconductor.

"This achievement can give full play to the advantages of fast switching speed and low loss of the third generation semiconductor devices, which is of great significance for the development of high power and extremely high power density converter equipment." Xin Yang introduced.

Semiconductor components used in experiments in Xin Yang.

Power semiconductors are widely used, ranging from high-speed trains to mobile phone chargers.

"Almost everything involving electric energy conversion requires the participation of power semiconductors." Xin Yang said, "But our country once lagged far behind Europe in power semiconductor devices including IGBT (Insulated Gate Bipolar Transistor)."

IGBT has long been monopolized by developed countries. In 2009, in order to learn advanced semiconductor knowledge, Xin Yang studied for master’s degree and doctor’s degree in Imperial College London and Cambridge University.

During his stay at Cambridge University, Xin Yang firmly decided to return to China in contact with CRRC Zhuzhou Institute and related companies. "Many of our own technologies are not advanced, so we have to look at others’ faces. That feels terrible. " Xin Yang said, "At that time, I felt that the country urgently needed this technology, and it was time for me to realize my self-worth and serve the motherland."

Yang Xin takes students to work in the laboratory.

In 2015, Xin Yang returned to his native Hunan from Britain. In 2018, he was hired as a professor and doctoral supervisor at the School of Electrical and Information Engineering of Hunan University. Hunan University’s relatively complete incentive system for young teachers and the free and open academic environment at the foot of Yuelu Mountain have given Xin Yang great impetus.

In recent years, Xin Yang has presided over or participated in several national scientific research projects, published more than 40 high-level papers and applied for more than 20 invention patents.

"I went out with an initial intention to study for my country. After I came back, I felt that the country, especially Hunan, attached importance to talents. Only by redoubling efforts and making achievements can we live up to the expectations of the party and the people." During the conversation, Xin Yang said many times that he wanted to contribute to the country’s breakthrough in key technologies.

In Xin Yang’s view, his academic achievements can not be separated from the support of relevant national policies. He was selected into the relevant national talent plan, and his learning experience in the team of Luo An, an academician of China Academy of Engineering, also benefited from the Hunan Young Talents Support Program.

Xin Yang is with his students.

Nowadays, the importance of chips to modern industry is becoming more and more prominent, and talents are the key to technological leadership. Xin Yang pays special attention to the matter of taking students, and his latest research results include many master students. "Academician Luo An has given me a lot of help. As a teacher, I should also teach my students what I have learned without reservation. The happiest thing is that my students are better than me academically."

In the next six months to a year, Xin Yang will focus on building a new reliability evaluation method for power semiconductors. "At present, the evaluation of power semiconductors is still relatively extensive. We hope to reach the degree of calculation reliability and know the service life of IGBT components more accurately, and then deduce more advanced and reliable power semiconductor packaging technology."

In addition to constantly pursuing the optimization of chip performance indicators, looking to the future, Xin Yang wants to make some subversive achievements in originality theory. "Time is still tight." Xin Yang ridiculed his increasingly backward hairline. After devoting himself to scientific research, Xin Yang almost had no entertainment activities. "But doing research with students is very happy, and I don’t feel tired when I work overtime."

"I hope that when the country stands at the forefront of the world in the field of power semiconductors one day, I can be proud to have contributed a little to it." Xin Yang said.
