Personal introduction of Qian Weichang

Qian Weichang was born in Wuxi, Jiangsu from October 9, 1912 to July 30, 2010.

He was the president of Shanghai University and the director of Shanghai Institute of Applied Mathematics and Mechanics. Qian Weichang studied in the Department of Physics of Tsinghua University and the Institute of Physics of Tsinghua University from 1931 to 1937. In 1937, he taught at Tianjin Yaohua Middle School and in 1939, he taught at Southwest Associated University. In 1942, he received a doctorate in science from the Department of Applied Mathematics at the University of Toronto, Canada. From 1942 to 1946, he served as a research engineer at the Jet Propulsion Institute of the California Institute of Technology in the United States.

He returned to China in 1946 and served as a professor at Tsinghua University. In 1949, he served as member of the Standing Committee of the Tsinghua University Academic Affairs Committee and vice provost. In 1952, he served as the provost of Tsinghua University and joined the China Democratic League in 1952. In 1954, he served as director of the Mechanics Research Office of the Institute of Mathematics, Chinese Academy of Sciences. In 1955, he was elected as a member (academician) of the Chinese Academy of Sciences. In 1956, he served as Vice President of Tsinghua University and was elected as a foreign academician of the Polish Academy of Sciences in the same year.

Biography

Qian Weichang is mainly engaged in research work in applied mathematics, mechanics, physics and Chinese informatics. Qian Weichang created the intrinsic unified theory of plates and shells and a system of nonlinear differential equations for shallow shells. He has made significant contributions in waveguide theory, singular perturbation theory, lubrication theory, ring shell theory, generalized variation principle, finite element method, and armor-piercing mechanics. , large motor design, high-energy batteries, aerodynamics, Chinese informatics and other aspects have contributed.

From 1934 to 1935, Qian Weichang and Gu Hanzhang measured atmospheric electrical parameters in Beijing. From 1935 to 1939, he did spectral analysis and X-ray diffraction of rare earth elements under the guidance of Wu Youxun, and studied solution theory under the guidance of Huang Ziqing. From 1940 to 1941, he studied the intrinsic unified theory of plates and shells in Canada. From 1941 to 1942, he studied the reactance in radar waveguides and collaborated with A. Weinstein to study the vibration of fixedly supported tension square plates.
