Xiong qinglai (1893.9.11~1969), a mathematician in China, was born in Maitreya, Yunnan. 19 1 1 year to study in colleges and universities in Yunnan province, 19 13 years to study mining in Belgium. 19 15 to 1920 studied at the University of Bourne in Greno and the University of Montpellier, and obtained the Master of Science degree. 192 1 returned to China in, and successively served as a professor at Nanjing Southeast University, Nanjing Normal University and Tsinghua University. 193 1 went to France to study again, specializing in function theory, and returned to China in 1934 after receiving his doctorate, and still taught in Tsinghua University. 1937 President of Yunnan University. 1949 attended the UNESCO general conference in Paris, and then stayed in France to engage in mathematical research. 1957 came back from Paris and worked in the Institute of Mathematics of China Academy of Sciences. He mainly engaged in the research of function theory and defined an "infinite order function", which is called "Xiong's infinite number" internationally. 1930, when he was the head of the Department of Mathematics at Tsinghua University, he found Hua's name in academic magazines. After learning about Hua's self-study experience and talent in mathematics, he resolutely broke the routine and let Hua, who had only junior high school education, enter Tsinghua University. Under his training, Hua became a world-famous mathematician. Many famous China scientists, such as mathematicians Xu, Duan Xuefu, Zhuang Qitai, physicists, Qian Sanqiang, Zhao Jiuzhang and chemist Liu Gang, are all his students. In the 1960s, he was over 70 years old, and he was still teaching two young people who later became famous mathematicians, namely Yang Le and Zhang Guanghou. Therefore, he is not only a pioneer of modern mathematics in China, but also a Bole who knows swift horses.

Wang Xiji (192 1~) is a senior academician of China Academy of Sciences and a famous expert in space return technology. Dali, Yunnan, male, Bai nationality, born in 192 1 year. 1937 ——1938 graduated from Kunhua Advanced Industrial Vocational School (formerly the predecessor of Yunnan Institute of Technology), 1942 graduated from department of mechanical engineering, The National SouthWest Associated University; 1949 received a master's degree from Virginia Tech. From 65438 to 0950, he returned to China and served as an associate professor and professor in Dalian University of Technology, Shanghai Jiaotong University and Shanghai University of Science and Technology. After 1965, he served as the chief engineer of Shanghai Electromechanical Design Institute, the Seventh Machinery Department, the vice president of China Academy of Space Technology, the director of the Science and Technology Committee, the chief designer of China's recoverable satellite series, the honorary chairman of China Space Science Society, and the academician of the International Academy of Astronautics. At present, he is the chief expert of small satellite and the chief designer of double star project. 1993 was elected as an academician of China Academy of Sciences.

Dai Yongnian (1929.2.9-). Expert in vacuum metallurgy of nonferrous metals. Native place: Tonghai County, Yunnan Province. 1947 entered the Department of Mining and Metallurgy of Yunnan University; 1948 12 Join the "Yunnan Democratic Youth League" (leader of the underground party); 1951September to1954 August, Assistant Professor, Department of Mining and Metallurgy, Yunnan University; 1August, 954 to1August, 956, studied in the postgraduate class of Metallurgical Department of Central South University; 1956 graduated from the graduate class of metallurgical department of Central South University, 1956 has been teaching at Kunming University of Science and Technology (now Kunming University of Science and Technology) since August, in which: 1979 to 198 1 year founded the vacuum metallurgical laboratory and served as its director; From 198 1 to 1984, he served as Minister of Metallurgical Department; 1982, director of vacuum metallurgy and materials research institute; 1999 was awarded as an academician of China Academy of Engineering, and in 2002, it was awarded the highest award of Yunnan science and technology-Outstanding Contribution Award. He is currently a professor and doctoral supervisor of Kunming University of Science and Technology, director of the Institute of Vacuum Metallurgy and Materials of Kunming University of Science and Technology, and director of the Academic Committee of Yunnan Key Laboratory of Vacuum Metallurgy of Nonferrous Metals. The national key discipline of "Nonferrous Metallurgy" and the leader of the key discipline of "Vacuum Metallurgy" in Yunnan Province have established the Institute of Vacuum Metallurgy and Materials, trained more than 40 doctoral and master students successively, undertaken and completed dozens of scientific research projects, and engaged in the teaching, scientific research and engineering research of non-ferrous metal vacuum metallurgy for a long time. The theory of metal vacuum gasification separation is developed, and the theoretical system of non-ferrous metal vacuum metallurgy is formed. Firstly, a new pyrometallurgical refining technology for crude lead was successfully developed, which simplified the refining process. The invention of that internally heat multistage continuous distillation vacuum furnace has been popularized and apply in more than 40 domestic units and countries such as Brazil, Bolivia, Southeast Asia, etc., and part of the traditional production processes of tin, lead and zinc metallurgy have been transform, and accumulated economic benefits of 1 100 million yuan have been created; The horizontal vacuum furnace and related technologies have been successfully developed, and a large domestic non-ferrous metal vacuum metallurgical workshop has been built in Shaoguan Smelter. Won 28 national and provincial awards, including the second prize of national technological invention 1, the second prize of national scientific and technological progress 1, and the fourth prize of national invention 1. Yunnan Science and Technology Outstanding Contribution Award 1 item (3 million yuan), 4 first-class and second-class prizes for provincial and ministerial-level scientific and technological progress, and "94' Scientific and Technological Achievement Award" 1 item of China Vacuum Society. Won the honorary titles of "National May 1st Labor Medal", "National Advanced Scientific and Technological Workers in Colleges and Universities", "Model Worker in Yunnan Province" and "Outstanding Scientific and Technological Talents with Outstanding Contributions in Yunnan Province" and enjoyed special government allowances. Published more than 0/00 papers/kloc, of which more than 30 papers were included by SCI, EI and ISTP. Published 7 academic monographs. Obtained 1 1 invention patent and utility model patent.
