The research of this paper includes : ? high - speed photography and flash x - ray radiography are both used to capture the process of al shell ' s great deformation under low pressure . front illuminations are used to get the development of the fracture on the al shell . the relative energy release is analyzed from overpressure curves measured with some sensors 本文的研究内容主要包括： ?在受试炸药经历低应力大变形过程的susan试验中，同时采用高速摄影、闪光x射线照相对弹体的撞靶过程进行了拍摄，得到了壳体膨胀变形过程图像，并使用前照明技术观察到了铝壳表面产生的裂纹及其发展变化过程；从压力传感器测量的空气冲击波超压曲线，获得反应释放总能。
