摘　　要：针对新研制的火炮炮膛免启封封存膜在榴弹射击过程中对内弹道性能造成的影响,进行了数学建模分析,对模型采用经典内弹道学理论进行求解,得出在不同膜厚情况下的膛内压力曲线,与正常射击情况比较后,认为对内弹道性能影响可忽略,对封存膜的推广应用提供了一定的理论依据。This article builds a mathematic model,for the new prepared unremove seal film on the in-bore of tank gun which affects the inner-ballistic performance during the shrapnel's firing process and analy- ses its effect.The model is resolved through classical ballistics theory.Finally the chamber pressure curve and the velocity curve under the different thickness of the film are obtained.Comparison is made of this result with that in the common condition,which shows that on the effect on inner-ballistic per- formance can be ignored.And the unremove seal film is provided with theory basis for its spreading and application.
