| 摘 要： | 本文在假定气态爆轰产物的无粘、绝热、并忽略炮孔径向动力膨胀条件下，以敞口炮孔高温、高压气态爆轰产物孔口喷流的一维等熵非定常连续运动的理论分析、计算为基础，根据炮孔内爆轰产物的状态方程，由爆轰产物的初始状态参数，从理论上确定因孔口喷流所引起的炮孔平均压力随时间变化的历程．

| Abstract: | This paper start form the thcorctical analysis of the one-dimension isentropic unsteady flowof explosion products with a high temperature and pressure out bursting from the borchole. Inaccordance with the state equation and the initial state parameters of the explosion products, the pressure course of borehole changing with time is obtained. Finally, an example is given to show the use of the method proposed in this paper. |
