摘　　要：本文采用绝热量热实验方法模拟了某工厂的干燥鞭炮和潮湿鞭炮的绝热反应过程,得到了绝热反应温度随时间的变化曲线,通过数据校正和分析,得到了鞭炮在受潮后初始放热温度降低的结论。最后用伪逆矩阵法计算潮湿鞭炮第一次放热反应的活化能E和指前因子A,用热惰性因子修正绝热参数,为防止发生爆炸事故提供了理论依据。In order to prevent fire and explosion accident caused by firecrackers, dry and moist firecracker samples are tested by Accelerating Rate Calorimeter (ARC). The results show that dry sample react faster than moist samples, and moist firecrackers are easier to reaction. Then Pseudo-inverse matrix method is used to calculate dynamics parameters and the measured data are modified by considering of thermal inertia factor of ARC. The results show that the initial exothermic temperature for moist firecrackers is 49.06℃ with the maximum temperature being 573.83℃ and the time to maximum self-heating rate being 119.83min.
