摘　　要：介绍了用平均膛压、弹底压力和膛底压力描述的金属风暴耦合内弹道方程、耦合内弹道次要功系数,以及用绝热方程描述的火药气体后效期。分别在同装药量和优化装药结构条件下,计算典型耦合内弹道参数,并解释其物理现象。证明斯鲁哈斯基公式不适用于耦合内弹道选药计算,需要利用耦合内弹道程序修正药量。It was presented that the coupling interior ballistics equations and subordinate work coefficients were described by mean bore pressure,pill bottom pressure,bore bottom pressure,and the powder gas after-effect period was described by adiabatic equation for Metal Storm.The typical coupling interior ballistics parameters were computed and their physical phenomena were explained on the condition of equal powder amount and optimized powder.It is proved that the Sluhartsky correction formula is unsuitable for adjusting the powder amount in coupling the interior ballistic test;the interior ballistic computing program is needed to adjust the powder amount.
