子弹散布 meaning in English

bullet dispersion

On evaluating the hitting precision of a missile which throws sub - missiles , it is a key question to estimate the normal distribution parameter of the sub - missile dispersion center
对带有均匀抛撒子弹头的常规导弹的命中精度评定，其关键在于子弹散布中心分布参数的准确估计。

The usual method is , to find a sub - missile disper firstsion center first from each group data of the sub - missile ' s falling point coordinate , then to estimate the parameters according to a few data of dispersion center using the classical statistic method
通常的方法由每次试验的子弹落点数据获得一个子弹散布中心，再由少数的几个散布中心数据、运用经典的统计方法求散布中心的正态总体分布参数，其不足之处在于小样本条件下采伪的概率很高。
