该方法以带炮口制退器三维非定常流场的数值模拟为基础，通过计算火药气体流经制退器时火炮身管的受力，计算出身管在火药气体作用下的最大自由后坐速度，进而根据制退器效率的定义得到炮口制退器的效率。

Two small-arms protective inserts may also be added to the front and back of the vest, with each plate designed to stop up to three hits from 7.62x51mm NATO M80 ball ammunition, with a muzzle velocity of 2,750 feet per second (838 m/s).The E-SAPI plates are thicker and heavier than the normal SAPIs, but they offer increased protection from 7.62mm M2 armor piercing ammunition.

上面这段是说拦截者加装SAPI防弹插板以后，每块插板可以保证防住最多3发7.62x51mm M80普通弹的几乎零距离的命中，而改用更新式的E-SAPI插板就可以防护7.62x63mm（也就是二战伽兰德步枪用的。30-06步枪弹）M2钢芯穿甲弹的直击。

Also, the smaller turrets (armed with TMG's) were the same. At first the T-28 was armed with a 76.2 mm short-barreled tank gun: KT-28. Later versions received a more powerful tank gun L-10 with a barrel length of 26 calibers and muzzle velocity of
