摘　　要：采用差示扫描量热仪(DSC)研究了RDX对混合炸药体系的热分解性能的影响,用Kissinger法和Ozawa法计算并分析了其热分解动力学参数。结果表明,加入RDX后的混合炸药体系的初始反应温度、峰温、表观活化能、指前因子、自加速分解温度、热爆炸临界温度均随着RDX含量的增大而降低,说明了RDX的加入使混合炸药的热安全性变差了。The influence of RDX on the thermal decomposition behaviors of composite explosive system were studied by differential scanning calorometry （DSC）, and the thermal decomposition kinetic parameters were calculated by Kissinger and Ozawa methods. It was found that the initial and the peak temperature, the apparent activation energy, frequency factor, self-accelerating decomposition and critical temperature of the thermal explosion all decrease with the increase of RDX amount. The results showed that the thermal safety become lower after the adding of RDX.
