湖南株洲陈斌读者: 弹壳虽然较薄,但由于武器发射时,自动机与枪膛成闭锁状态,弹壳在弹膛内,弹壳壁紧贴枪管弹膛,虽然火药气体压力作用于弹壳,却不会炸烂弹壳。大多数弹壳是冷冲压加工出来的,也有少数弹壳是机加或通过其它方法加工出来的。 Chen Bin, Zhuzhou, Hunan Readers: Although the shell is thinner, the automaton and the barrel become locked when the weapon is fired. The shell is in the shell and the shell wall is in close contact with the barrel of the barrel. Although the gas pressure acts on the shell, Will not scavenge the shell. Most casings are cold stamped out and a few are machined or machined out by other means.
