文中针对利用少量样本进行检验造成平均弹道一致性检验判据中正态特性发生变化等问题,利用正态性检验、稳健估计等统计学方法,对试验样本进行了预先检验和数据预处理,重建了检验模型,得出了新的检验方法,并对改进后的检验方法进行了验证,结果表明该方法具有更好的可靠性和适用性。

Aiming at the question of the test criterion of average trajectory consistency, it thinks out that small sample is the reason of normal characteristic's charge. The pretest and data pretreatment is give with normality test and robust estimation for test sample. It rebuilds a test model and obtains a new test method. According to the testing result, the method has high applicability and reliability.
