Yan Shilong a, Feng Shuyu a, Jin Xiaogang b ( a. China Academy of Railway Science,Beijing,100081) ( b. Laboratory for Shock Wave and Detonation Physics Research, Institute of Fluid Physics,CAEP,P.O.Box 523,Chengdu,610003)  
By means of high speed photograph method,the developing process of the broken region in PMMA by detonation of a cylindrical charge is studied in this paper.The result shows that the broken region by detonation consists of two parts,the cylindrical part and the two end parts.The developing characteristic is that the developing speed slows down from the cylinder to both ends.
