摘　　要：在传统的关于液固撞击的激波理论模型中，引入矢量分析的方法，考虑到高速度撞击时，液体运动的迁移性和非线性效应，以及固体的可变形性，提出了一个适用于高撞击马赫数的无量纲激波理论模型。该模型能够计算出所有撞击参数，计算结果与实验数据吻合良好。模型所导出的计算方法物理意义明确，简明准确，适用范围宽广，且便于工程上制成图表查用。Vector analysis is introduced into the traditional shock model for the liquid solid impact problems. A better relationship that takes account of the convective and nonlinear aspects of the liquid motion and the elasticity of the target is determined from the fundamental equations of continuity, momentum and state. All impact parameter can be calculated and good agreement is found with available experimental data for water.
