摘　　要：针对两种命中误差指标在轴向偏差独立同分布情形下的关系进行了推导,并运用仿真试验进行验证,说明了推导的正确性。对独立非同分布以及非独立非同分布的一般情形进行了进一步的拟合分析,得到了两种命中误差指标关系的拟合多项式。The internal relation between two kinds of lateral hit error--CEP and standard deviations is derived when the coordinate of impact points submit to an independent distribution. The simulation method is used to research the relation based on curve fitting. The relation is approved by simulation results. The relation is analyzed deeply when the coordinate of impact points submit to a dependent distribution. The results are available for the conversion between CEP and standard deviations.
