镜子的动量就不可能是绝对0，这会影响recoil的测量，要知道，
这个待侧动量是两倍光子的大小，也就是2h/ramda
定位精度*动量精度=dx*2h/ramda>=h/2
为了能测recoil，不可能定位精确于ramda/4,正好足够毁了整个条纹

Mukden Arsenal after WWII
April 3, 2017 jwh19752 Comments
(Zhang's Gate, the old entrance to Mukden Arsenal)
For people interested in Japanese firearms of WWII, the name Mukden Arsenal
is familiar. The history of the facility after Japan's defeat is less well
known. Under various names, it did survive for some time, producing an odd
mix of WWII weapons after the war's end.

美国为何宣布撤军呢？按美国总统特朗普的表态，是因为是美国打败了盘踞在叙

土耳其总统埃尔多安。

发帖数: 1 | 31 炮口制动器或者后座辅助器, 炮（枪）口制退器（muzzle brake；recoil compensator
）是轻兵器的枪管上或者火炮炮管上的装置的一种，俗称“防火帽”（但是这个称谓有
误，详见下文）。这种装置的设置目的在于将弹药中所燃烧推动弹头的气体重新定向排
放，如此可以减轻枪支或火炮的后座作用（降低后座力），减少枪/炮管射击时的上扬
，大幅增加射击的可控性和舒适性，尤其需要快速射击的时候。并且能使较小的载具装
载更大口径的火炮。
和任何枪/炮口装置一样，制动器对武器精度都会产生影响。制动器在制造时的精度误
差会影响射击准确性（许多顶级竞赛/狙击步枪为了保证精度就不装任何枪口装置）。
由于制动器直接处于弹药产生的气体的冲击之下，如果存在制造缺陷，会导致风险（曾
经就有苏联高级军官差点被坦克原型车上碎裂的炮口制退器杀死的事故）。在脱壳弹药
（比如APFSDS）使用越来越频繁的今天（尤其是大口径武器），有时制动器会对“脱壳
”过程产生干扰，这也可以在一定程度上解释为什么当代战车炮威力越来越大却越来越
少使用炮口制动器。
所以，综上所述，制动器如非必须，则装上往往会弊大于利。 |
