通过差示扫描量热法( DSC)测定了不同比例Al￣RDX混合炸药的热分解过程，分别获得不同升温速率下的热分解峰温。根据Kissinger方程计算了不同比例Al￣RDX混合炸药热分解的表观活化能和指前因子，研究了不同比例Al￣RDX对其混合炸药热分解表观活化能Ea 的影响。结果表明：随着Al￣RDX比例的逐渐变化，热分解活化能Ea 先下降后升高。从理论上导出了符合试验结果描述的热分解活化能Ea与Al￣RDX比例的关系式。同时，发现不同比例Al￣RDX混合炸药的热分解活化能Ea 与指前因子的对数lnA之间存在着动力学补偿效应。

[ ABSTRACT] The decomposition of different proportions of Al￣RDX hybrid explosives were determined by differential scanning calorimetry ( DSC ) , and the decomposition kinetic parameters( Ea and lnA) were calculated by means of Kissin￣ger equation. The effects of Al￣RDX ratio on the thermal decomposition activation energy Ea were studied. The results indi￣cate that after initial decline the Ea values tend to rise with the decreasing of Al￣RDX ratio. A good relation, which is in agreement with experiment results and can represent the correlation of Ea with the mass ration of Al￣RDX, is derived from theory. Additionally, it is found that a compensation effect exits between the DSC decomposition kinetic parameters ( lnA and Ea ) for all the Al￣RDX samples.
