考虑到某些弹种在靶场试验时的局限性，本文探讨了在火炮及装药结构不变时，弹丸质量对最大膛压及炮口初速的影响，结合靶场试验结果，给出了最大压力及初速随弹丸质量变化的经验关系式；利用该经验关系式，对两种不同弹的装药内弹道性能测试进行修正，其结果与试验值基本一致，从而为减少实弹射击节约经费及靶场试验修正提供了一种新方法．
Taking into account the limitations of some bullet in the shooting range test, this paper discusses the impact of projectile mass on the maximum chamber pressure and muzzle muzzle velocity when the artillery and charge structure are invariable. Combined with the shooting range test results, the maximum pressure And the initial velocity with the projectile mass change empirical relationship; the empirical relationship between the two different bullets charge internal ballistic performance test is amended, the results are consistent with the experimental value, in order to reduce the live firing of saving funds and shooting range test Amendment provides a new method.
