The design of cannon - shot muzzle velocity instrument based on labview and virtual instrument techonlogy 一种基于虚拟仪器技术的弹丸初速度测试仪的设计
Such muzzle velocity reduction and weight coefficient can be marked out one by one and be made up into the curve board 将每一条曲线对应的初速减退量、曲线上各段的权重系数一一标出，并可制成曲线板。
The reasons causing gun propellant charge temperature coefficient and the methods of reducing charge temperature coefficient and increasing gun projectile muzzle velocity have been studied 研究了火炮装药温度系数形成的原因以及降低火炮温度系数提高弹丸初速的基本原理和措施。
If we take out several measuring points along the bore axis and work out the amount of bore wearing , we can consult and calculate the muzzle velocity reduction of the piece by reference of the curve board 沿膛轴方向取若干个测点，当测出各点的炮膛磨损量后，即可从曲线板中查取计算出火炮的初速减退量。
On the similitude artillery , 7 items of shooting tests were proceeded . these items included : muzzle velocity of projectile , pressure of gases , recoil force , efficiency of muzzle brake , muzzle shockwave , dynamic stress , stability 在模型炮上进行了7个射击实验项目，实验项目包括：初速、膛压、后坐阻力、炮口制退器效率、炮口冲击波、动态应力、稳定性。
From the 508 mm barrel of the m16 , the fragmentation effect lasts out to 150 m to 200 m but the short ( 368mm ) barrel of the m4 develops a lower - muzzle velocity , pulling the fragmentation limit down to 50 m to 100 m M16步枪508毫米的枪管发射后，碎片效果只在150米到200米的距离内出现，而m4卡宾枪368毫米的枪管使用了低初速枪口，将碎片有效距离减少到了50米到100米。
As for one specific gun ammunition system , by use of the established mathematical models the curve of the bore wearing , the muzzle velocity reduction related to that kind of curve and the weight coefficient at each section of that curve can be simulated 对于某一火炮弹药系统，利用建立的数学模型可模拟出炮膛磨损曲线及每一条曲线所对应的初速减退量、曲线上各段的权重系数。
