| 摘 要： | 本文从分子运动论出发，考虑到高密度下分子碰撞及高温下分子间作用的特点，提出了简化的三分子碰撞模型，并引进屏蔽效应，给出了描述高压下火药燃气实际状态行为的多项式型状态方程式。在800 MPa的压力范围以内，本文对不同组分的发射药进行了计算，其计算压力与实验有较好的一致性。比目前美国三军所用程序BLAKE编码的计算结果有所改进。

| Abstract: | Based on the kinetic theory of molecules and in consideration of high density molecular collision and molecular interaction at high temperature. we propose a simplified model of three molecular collision and introduce the shielding effect of the molecule In this way, an equation of state of polynomial type is set up that describes the real performance of gun propellant gas under high pressure. We calculated the pressure up to 800 MPa for the gun propellants. with different composition. The calculated pressure is in excel- lent agreement with the experimental data and is better than those calculated by the BLAKE code and used by the US Army. |
