| 摘 要： | 利用自行设计的热爆炸实验装置，测定了以ＲＤＸ、ＨＭＸ、ＨＭＸ／ＴＡＴＢ、ＴＡＴＢ为基的粘结炸药在三种尺寸下的有量纲热爆炸参数（临界温度、延滞期）；利用Ｓｅｍｍｅｎｏｖ参数，求得了上述炸药热爆炸表现活化能，讨论了临界温度与圆柱体高和半径的关系、延滞期与超临界程度的关系、并预测了炸药在一些较大尺寸下的临界温度。

| Abstract: | The thermal explcoion Parameters (criticaL temperature,time-t0-explosion) ofplastic bonded explosives based on RDX,HMx,NMX/TATB and TATB in three sizes anr measured.In this paper,the thermal explosion activation energy is calculated,the relationship of critical temperature with radius and height of the cylinder and the relationship between time-tO-explo-sion and supercritical degree by utilization of Semmenov parameter are discued, and the criticaltemperature of explosive in large size is pred icted. |
