摘　　要：采用一维流体动力学、与时间相关的JWL爆轰产物状态方程以及压力指数为 1 /6的反应速率方程,计算分析了铝化炸药水下爆炸冲击波特征参数对反应速率的依赖关系。结果表明,反应速率常数存在阈值,只有反应速率足够大,才能充分利用爆炸能量。根据铝粉粒度与反应速率常数的相关性,通过控制铝粉粒度可以设计不同的能量输出特性。Using the one-dimensional hydrodynamics code and the time-dependent JWL EOS, using a pressure exponent of 1/6 in the pressure-dependent rate law, this paper calculates the relationships between characteristic parameters of shock wave and reaction rate for underwater explosion of aluminized explosive. The results show that there is a critical value in the rate constants,and that the blasting energy can be used efficiently only if the rate constant is larger than the critical value. In the view of the relationships between aluminum size and the constant, we can design different energy output characteristics through dominating aluminum size.
