摘　　要：影响子母弹开舱高度的高低散布的因素有初速散布、射角散布、弹道系数散布和引信装定时间散布。给出了各因素对开舱高度高低散布影响的计算方法,运用误差合成的方法得出子母弹开舱高度综合高低散布及各因素占综合高低散布影响比重的计算公式。通过弹道方程计算了某弹丸不同高度、速度和射角下的各高低敏感因子。在一定的条件下计算并分析了某火炮子母弹开舱高度的高低散布随高度、初速和射角的变化及各因素所占的比重。提出了子母弹最低开舱高度的确定方法。Factors influencing the vertical dispersion of height of a carrier projectile at opening point are muzzle velocity dispersion, departure angle dispersion, ballistic coefficient dispersion and fuse time setting dispersion. Calculation method of vertical dispersion of opening height influenced by each factor is given. A synthetical vertical dispersion of opening height expression and the proportion of each factor in syntheti- cal vertical dispersion are obtained by means of errors compound. Vertical sensitivities of a certain carrier projectile with different heights, initial velocities and departure angles are given by ballistic calculating. Variation of vertical dispersion of opening height and the proportion of each factor in synthetical vertical dispersion with heights, initial velocities and departure angles are calculated and analyzed. Method of determining the minimum opening height of carrier projectile is given.
