摘　　要：用DSC、DTA和TG-DTG技术测定了RDX和HMX热分解的动力学参数。RDX和HMX在不同的分解阶段有不同的动力学参数和机理函数,其分解过程和动力学参数受试验条件、样品状态和试验方法的影响很大,但这些参数之间存在"动力学补偿效应"和"等动力学点"。The kinetic parameters of thermal decompositions of RDX and HMX explosives were obtained by using DSC,DTA and TG-DTG. It is shown that the differential kinetic parameters and mechanism functions appear in various stages of thermal decomposition for RDX and HMX. The decomposition processes and kinetic parameters of RDX and HMX are markedly affected by test conditions, specimen state and test method, and the 'kinetic compensation effect'and 'isokinetic points(temperatures)' exist in these parameters.
