一、引言 随着战争以及武器的发展,要求武器在某种特殊战势情况下的降噪量标准越来越高。通用的方法是女装一个高效的消声器,即在原有武器上安装一个可拆装的、消声量大于20dB的消声器。这相当于在武器发射的瞬间,消耗掉火药气体剩余能量的90％。这一要求不仅增加了消声 I.

The common method is to wear an efficient muffler for women, which is to install a removable muffler with a muffler volume greater than 20dB on the original weapon. This amounts to 90% of the remaining energy of the gunpowder gas at the moment the weapon is launched. This requirement not only increases the noise cancellation
