超高速粒子碰撞的Swift，Lawrence　R　J模型的改进

The Improve of the Swift ,Lawrence R J Model on the Hypervelocity Particles Impact

改进了描述弹丸与带缓冲板的靶板间超高速碰撞现象的Ｓｗｉｆｔ，ＬａｗｒｅｎｃｅＲＪ计算模型，使该模型增加了确定靶板上受到碎片云团碰撞部分的范围大小及计算碎片云团碰撞靶板上各点的速度和质量面积密度两项新功能．

In this paper,the Swift,Lawrence R J calculation model has been improveed,which is used to discribe hypervelocity particles impact phenomena.The improved model has been add some new functions:①It can be used to determine the impact range of fragments cloud cluster-at the target.②To calculate the fragment cloud clustervelocity and mass area density of each point at the target in impact process.
