| 摘 要： | 用PDSC和TG-DTG研究了RDX和HMX的热分解，探讨了各种试验条件，包括试样量、升温速率和动静态高压等的影响。在分解过程中相态变化引起反应的加速是HMX的分解较RDX剧烈的主要原因，HMX的自加热和自催化也因此变得较RDX更显著。

| Abstract: | In this paper the thermal decompositions of RDX and HMX explosives were investigated by using DSC and TG-DTG. The influence of experimental condition, including sample size, heating rate and ambient pressure under static and dynamic pressure, on the thermal behaviors was considered. The exothermic decomposition of HMX is sharper than that of RDX, the reason mainly being the solid-liquid phase change occurring for decomposition of the former. Thus the self-heating and auto-catalysis of sample for HMX are stronger than those for RDX. |
