Zhang was mainly engaged in the experimental research of nuclear physics and comic ray physics and made prominent achievements. He identified the N.Bohr drop model and invented the polymitus spark counter. In the late 1940s, by studying the cosmic rays with the aid of a cloud chamber in the US, he confirmed that there is no strong interaction between the muon and nucleus and verified the existence of the muonic atom in his investigation of the muon absorption, thus initiating a new research topic about the muonic atom. He made important contributions to the resea rch on λ-hyperon and particle dispersion, the basic work of constructing Beijing Electron and Positron Collider, and the estab lishment of cosmic ray laboratory on mountains.

He became Member of the Chinese Academy of Sciences in 1957.

Mechanics scientist. Born in Rongcheng, Shandong Province. Graduated from Peking University in 1935 and stayed on doing graduate work. Received Ph.D. from California Institute of Technology, USA In 1945. Research professor and deputy director, Institute of Mechanics, Chinese Academy of Sciences.

In 1946, he and H.S. Tsien pointed out that in the transonic flow field, it is the upper critical Mach number of the coming flow other than the lower one that is significant. This finding played the decisive role in solving the technical problem of breaking through the “sonic barrier”. Around 1953, he devoted himself successfully to the study of interaction between the shock wave and boundary layer, obtained theoretical expressions for velocity and pressure in the interaction domain of supersonic flow and boundary layer, and improved the singular perturbation methods(namely, Poincare-Lightill-Kuo method). In the 1960s,he obtained significant achievements in detonation mechanics and hypersonic flow and made outstanding contributions to the development of nuclear weapons.

He became Member of the Chinese the Chinese Academy of Sciences in 1957.
