摘　　要：推导了火炮膛内截面积任意变化条件下拉格朗日问题的一般解。化简到膛内真实面积变化情况，获得了拉格朗日假设下膛内压力分布的精确解。在近似考虑膛内面积变化条件下获得了膛内压力换算的工程实用关系式。The general solution of the Lagrangian Problem in interior ballistics is derived under the assumed condition that the crocs-section area of gun barrel is given under the actual condition of cross-section area of the gun barrel.The practical relation ships of conversion among the breech pressure, the projectile-base pressure and the average pressure are obtained when considering approximately the variable cross-section area.
