摘要
通过用火炮外弹道测量的初速与标准初速的比率来评定火炮身管寿命。介绍了利用红外线发光管和光敏管测弹丸初速的方法,阐述了其工作原理,测量系统结构和测时仪的选择以及数据的处理。
The Barrel life of Cannon is assessed by the rate of the muzzle velocity of pill to the standard velocity. A method is introduced that the muzzle velocity is measured by the infrared photorectifier and photovaristor. The working theory, the configuration of the measure system, the choice of chronoscope and the DP is expatiated.
