比例膨胀假设条件下火炮膛内的压力分布规律

The Pressure Distribution Laws in Bore of Gun on the Condition of the Proportien Expand Hypothesis

重新推导了弹后空间压力分布规律的数学表达式，这对深入而准确地认识火炮膛内的各种物理过程具有重要意义。

In this paper, the mathematics formula of the pressure distribution laws at back of projectile space was established anew. It is very important for us to recognize the physical process of gun in bore deeply and accurately.
