Qian Weichang is a famous mechanic, applied mathematician, educator and social activist in China. He has written a lot in applied mathematics, physics and China informatics, and made outstanding contributions to the problems of plates and shells, generalized variational principles, perturbation methods, analytic solutions of rings, macro codes of Chinese characters, etc., which are highlighted in the following aspects: 1940 put forward that the nonlinear differential equation in the "intrinsic theory of plates and shells" is called "Qian Weichang equation", and the systematic perturbation method adopted in this theory. 1954' s theory of large deflection of circular thin plate won the second prize of 1956 National Science Award. 1979 won the second prize of 1982 national natural science award for the study of generalized variational principles; 1997 won the Science and Technology Achievement Award of Heliang Lihao Foundation on September 23rd. He is the author of Variational Method and Finite Element, Generalized Variational Principle, Armor-piercing Mechanics and the co-author of Mechanics of Elasticity. In view of his outstanding contribution to the cause of mechanics in China, together with Zhou Peiyuan, Qian Xuesen and Guo Yonghuai, he is recognized as the founder of modern mechanics in China.
In order to strengthen the exchange of achievements in the fields of applied mathematics and mechanics, Qian Weichang founded Appl. Math. Mecha warrior. -English education. And applied mathematics and mechanics of 1980. The contents of the two journals correspond to each other one by one, and the editorial board recommended the system. From its inception to the end of 2002, Mr. Qian has been the editor-in-chief. During this period, he not only personally determined the purpose of running the journal, personally reviewed all the manuscripts, but also personally set up the first editorial board. He is eclectic, promoted backward, and let young people take the lead in practice. At the beginning of the publication, more than 60 editorial boards were mostly young scholars, and most of them were fledgling associate professors or lecturers. Facts have proved that Mr. Qian has a unique vision and knows people well. Of the original 60-odd editorial board members, 8 later became academicians of China Academy of Sciences. In order to expand the influence of the journal, Qian Lao launched the editorial board and organized nearly 50 academic lectures on applied mathematics and mechanics all over the country in the name of the journal, with an audience of more than 20 thousand, which greatly promoted the development of the journal. In addition, Qian Lao also held numerous other international conferences, large and small, which played an indelible role in the development and spread of applied mathematics and mechanics in China.
