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具有重要的指导和实用价值而越来越受到重视。本文主要评述它们在岩石介质材料中的应用和最新进展，对它们的历史和今后的发展趋势也作了简要说明。Constitutive relation of material on high strain ration is gained by S.H.P.B or light air gun instrument now.The study indicate the loading of plane wave producer is more pratical 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 article introduces the applied achievement and new proceduren in rock materials.The history and tendency is simple introduced and commented on.
