摘　　要：通过分析影响含能材料热爆发参数的一些因素,指出了热爆发活化能用于全面评价热感度的重要意义。提出了可以通过热爆发活化能把5s爆发点试验与撞击感度试验相关联,并获得特性落高能的对数与热爆发活化能线性相关的线性经验式。The factors influencing the kinetic parameters of heat explosion of energetic materials were analyzed.It is pointed that the application of the activation energy of heat explosion to roundly evaluate the heat sensitivity is of great significance.It is proposed that the 5 s explosion temperature test would be correlated with the impact sensitivity test,by the activation energy of heat explosion.The results from tentative study show that the logarithm of characteristic drop height energy obtained from the impact sensitivity test can be correlated with the activation energy of heat explosion by a linear regression.
