摘　　要：压阻法是采用具有压阻效应的传感器测量冲击波波后各状态参数的方法,轻气炮是研究材料物态方程和冲击动力学行为的重要加载装置之一,将两种实验技术结合起来可以很好地测量材料在冲击加载下的冲击波剖面和材料的动力学参数。本文通过对某种材料冲击Hugoniot线的测量,研究了压阻法在轻气炮实验中的应用,得到了很好的实验波形和材料的冲击Hugoniot参数。The piezoresistive method is the way that adopt the sensor possessing the piezoresistive character measure the state parameter after shock wave, light-gun is a important loaded device on researching equation of state and impact behavior of materials, it is better to measure the shock wave profile and the dynamics parameters of materials under impact loaded. In this paper, studied the appliance of the piezoresistive method in light-gas gun experiments through measuring the shock Hugonoit line of one material, gained the best experiment wave shape and the Hugoniot parameters of the material.
