On the morning of May 22, 2021, a seminar on the construction of applied physics major in School of Physical Science and Technology was held in Conference Room 603 of Xipu Campus Complex Building. Professor Shen Huoming, deputy secretary of the Party Committee of the school, Director Cui Kai of the Academic Affairs Office, Liu Yu, secretary of the Party Committee of the college, Professor Jia Huanyu, Vice President, Professor Li Xiangqiang, Professor Xu Yuhong, Professor Liu Fusheng, Professor Wu Ping and other teachers and related experts attended the seminar. The meeting was presided over by Liu Yu, Party Secretary of the College. First of all, Secretary Shen Huoming said in his speech: "Relying on the first-class doctoral program in physics obtained in 2016, physics has made rapid development in recent years. The team led by Professor Xu Yuhong is jointly developing China's first quasi-ring symmetric star simulator with Japan's National Institute of Nuclear Fusion Science. At the same time, the School of Physical Science and Technology of Southwest Jiaotong University is the core construction unit of the National Major Science and Technology Infrastructure-Lasso LHAASO, and SPST has made important contributions. " "Applied physics majors deepen education and teaching reform by focusing on professional orientation and direction; Continuously optimize the talent training program; Carry out the integration of science and education, educate people cooperatively, and innovate the talent training mechanism. Then, Professor Xu Yuhong gave a report on the construction of applied physics major in Southwest Jiaotong University. It introduces the basic situation of physics and applied physics in detail, including the historical evolution of the discipline, the situation of teachers, the achievements of specialty construction in recent years and its characteristic advantages, etc. Then, the experts pointed out the shortcomings, construction ideas, key work and other aspects of professional construction. On-site teachers also asked experts for detailed advice on the confusion in professional construction. Finally, on behalf of the school, Director Cui Kai of the Academic Affairs Office thanked the experts for their careful guidance, and also said that the School of Physical Science and Technology would integrate existing resources, identify professional advantages, position accurately, and accelerate the promotion of professional strength. The seminar on the construction of applied physics specialty in School of Physical Science and Technology was successfully concluded.
