摘　　要：高应变率下材料动态本构关系，目前主要是通过Ｓ．Ｈ．Ｐ．Ｂ．装置和轻气炮装置来获得。研究［１］表明，平面波发生器加载更是一般爆破实验室适用的试验手段。Ｌａｇｒａｎｇｅ分析方法由于在材料动态性能实验分析中只有重要的指导和运用价值而越来越受到重视。本文主要评述这些方法在岩石介质材料中的应用和最新进展，对其历史和今后发展趋势也作了简要说明。Constitutive relation of material at high strain rate is gained by S.H.P.B.or light air gun instrument now. The study indicates the loading of plane wave producer is more practical test method in ordinary blasting laboratory. Lagrange analysis method is paid more and more attention, because it has more important guidance and utilized value in dynamic property experimental analysis of material. The application and new development in rock materials is mainly described in this paper. The history and tendency is briefly introduced.
