摘　　要：在科研和生产过程中,炮口测速装置要在弹道炮和战斗炮上进行初速标定和测速误差检测,两个平台上初速标定系数的一致性问题、测速误差合格判断问题、合理的检测样本大小问题,应用概率论和数理统计理论及方法、语言去解释和处理。从炮口测速装置的工作原理出发,分析了影响测速误差的主要因素,确定了初速标定系数一致性判别准则和测速误差合格判别准则,在给定置信水平条件下,确定合理的检测样本大小,分析方法和思路对火炮其他试验(如初速检测、立靶密集度试验、弹药运输前后弹道一致性试验等)数据处理、指标合格判定具有借鉴作用。In process of scientific research and production,muzzle velocity measurement device must be calibrated and the measured velocity error must be checked at the ballistic simulation gun and the combat gun.The check consistency of muzzle velocity calibration coefficients in the both guns,acceptability j udgment of measured velocity error and reasonable test sample size must be interpreted and solved by use of the probability theory and mathematical statistical method as well as the language in terms of probability and statistics.From the point view of the principle of muzzle velocity measurement device,the main factors that have influence on the measured velocity error were found out and analyzed.Judge criterion for consistency of calibra-ting coefficients and measured velocity acceptability at different guns were determined.Under the condition of the given confidence level,a reasonable test sample size was acquired.Some a-nalysis methods and resolved problem process may provide the reference for data processing and acceptability j udge of the other tests,such as muzzle velocity test,dispersion test with vertical target,consistency test of ammunition performance before and after transportation etc.
