摘　　要：为分析某型报废火箭炮弹内部梯黑铝混合装药唯象动力学性质,采用差示扫描量热仪测定了其热分解过程。分别得到梯黑铝炸药样品在5,10,20℃/min升温速率下的DSC曲线和相关特征数据。利用非模函数Ozawa方程,结合线性回归分析,计算了梯黑铝炸药的动力学参数,求得活化能Ea=59.035 0 kJ/mol,相关系数r=0.999 53。In order to analyze high explosive of TNT/RDX/AL from some abandoned rocket projectile warheads,its thermo-decomposition process was tested with the different scanning calorimetries.DSC curves and relative characteristic parameters were obtained with the warming rates of 5,10 and 20 ℃/min.Ozawa model and regression analysis were applied to calculate kinetics parameter.The activation energy was 59.035 0 kJ/mol and relative coefficient was 0.999 53.
