利用差热分析（ＤＴＡ）技术研究了黑索今（ＲＤＸ）、奥克托今（ＨＭＸ）和某些阻燃型添加剂（ＦＰＡ）二元混合体系的热分解唯象动力学，求得了唯象动力学能量Ｅ、Ａ、ｋ，同时分析了４００℃时，不同压力下反应速率常数ｋ与燃速抑制系数Ｋ间的线性关联性。
Differential thermal analysis (DTA) was used to study the phenomenological thermal decomposition kinetics of binary mixtures of RDX, HMX and some flame retardant additives (FPA) Kinetic energies E, A, k. At the same time, the linear relationship between the reaction rate constant k and the burning rate inhibition coefficient K under different pressures at 400 ℃ was also analyzed.
