摘　　要：研究了考虑膛内面积变化的再生式液体发射药火炮拉格朗日问题解,获得了不同位置压力更为准确的换算关系式,使再生式液体发射药火炮内弹道集总参数模型进一步完善。本文结果具有较普遍的意义。同时,证明了存在膛底边界运动和质量加入条件下的拉格朗日假设是比例膨胀假设的充分条件。Derives the solution of the Lagrange problem for the RLPG with variable cross-section barrel and obtains the conversion relationships among the breech pressure, projectile-base pressure and the average pressure. The results obtained are of general significance. It is proved that the uniform density hypothesis is the sufficiency condition for the proportional expansion hypothesis under the existence of the breech boundary motion and the mass jet.
