Ke has been engaged in the research and education for years and has made outstanding contributions in the fields of algebra， number theory and combinatorial mathematics. He obtained a series of significant theorems on the representation of a quadratic form as a sum as squares of linear forms. On the Diophantine equations， he solved the quadratic case of the Catalan conjecture， which has history of more than 100 years， and gained a number of important results. In Combinatorial theory， collaborated with others， he gave the wellknown theorem on the intersection sets of systems of finite sets， i.e Erdos-Ko-Rado theorem， which opens the way for the rapid development of the extremal set theory .Moreover， he has made grate and effective contributions to the education in China.endprint

Physicist. Born in Suqian， Jiangsu Province. Graduated from Tsinghua University in 1938. Received Sc.D. from California Institute of Technology， USA in 1943.Professor， Peking University， and research professor， Institute of Theoretical Physics， Chinese Academy of Sciences.

In this early career， Hu devoted himself to the study of theory of turbulent flow in fluid mechanics. In the 1940s and 1950s，he made deepgoing studies in the nuclear force theory for meson and generalized relatives， S matrix theory quantum electrodynamics and particle theory，highenergy multiparticle generation theory and strong interaction theory， and achieved significant progress .In the mid 1960s，together with Professor Zhu Hongyuan， he led the work of establishing and advancing the theory of straton model for hadron internal structure. Relevant problems were systematically studied and series of original results were obtained .He analyzed a large number of new hadron and new phenomena disclosed in the highenergy physical experiments and went future into the motive mechanism of hadron structure and strong actions.

He became Member of the Chinese Academy of Sciences in 1955.

周同慶 1907.11.17～1989.2.13

Zhou was mainly engaged in the research and education in the fields of spectroscopy， gas discharging spectroscopy and gas discharging plasma physics and was respected as the pioneer in spectroscopic study in China. In the 1930s，he developed a new type of low voltage arc illuminant and carried out investigations on the Inverse-Stack effect of Rb and Cs atomic spectrum， molecular spectrum and molecular structures. In the 1940s， he made important achievements in the study of physical approaches for measuring river depth and created the equipment for determining the depth of water and locating submerged reefs. He also made significant contributions in jointly developing high-vacuum tubes， X-ray and high-pressure rectifier tubes. He established and made deepgoing investigations on the space discharge plasma spectroscopy.
