枪弹初速下降对弹道高影响的试验研究

TEST MEASUREMENT OF INFLUENCE OF CARTRIDGE MUZZLE VELOCITY REDUCTION ON BALLISTIC HEIGHT

在一项科研试验中发现，散装和纸盒包装的枪弹，经过较短时期的贮存，其初速出现较大的下降，文中探讨了枪弹初速下降量与弹道高的变化关系，为长期贮存后的枪弹提供合理的使用范围。

in a research experimpent,we found that after short storage of bulk and box packed cartrideg,its muzzle relocity tends to decline.In order to provide reasonable use limits after long storage,the relations between muzzle velocity and ballistic height are discussed in this paper.
