中文摘要：
采用DSC—TG联用热分析技术以升温速率分别为2．0，2．5，5．0，7．5，10K·min^-1对五种乳化炸药热分解特性进行了研究，通过非模函数Ozawa法、Coats—Redfern法和Satava—Sest6k法计算了动力学参数。计算结果表明，三种动力学分析方法计算得到的活化能比较一致，五种乳化炸药热分解动力学参数计算结果可靠，推断出五种乳化炸药热分解反应的最概然机理函数。1^#样品对应随机成核和随后生长机理函数；2^#和5^#样品对应n=2／3的幂机理函数；3^#和4^#样品对应三维扩散机理函数。
英文摘要：
Thermal decomposition characteristics of five emulsion explosives were studied by DSC-TG at the heating rates of 2.0, 2.5, 7.5, 10 K · min^-1 ,and the thermal decomposition mechanisms were deduced by means of model-free function of Ozawa method and Costs-Redfern method and Satava-Sestak method. Results show that the activation energies calculated by the three methods are approximate, and the rationalities of thermal decomposition kinetic parameters of five emulsion explosives are verified so as to deduce the most possible mechanism functions of thermal decomposition characteristic of emulsion explosives. For sample 1, it is random nucleation and lateral overgrowth mechanism, for samples 2 or 5, it is Mample Power prienciple n = 2/3 mechanism, for samples 3 or 4, it is three dimension diffuse, 3D mechanism.
