英文摘要：

Detonation velocity and the leading shock front of two-dimensional steady-state detonation wave （2DSDW） of pressed TNT charges in two diameters are obtained experimentally. The distributions of pressure （P） and chemical reaction extent （ A ） in the 2DSDW along streamlines are determined by using 2-D C-J condition and conservation equations, in which the stream field of 2DSDW of pressed TNT can be researched. It is very important for the development of detonation theory and design of precision charging.
