摘要： 用详细的计算数据，在保持计算条件和总冲不变的情况下，分析了二级推力和三级推力方案时的方向密集度，从而得出了二级推力方案的方向密集度优于三级的结论，同时，提出了使方向密集度最小的最佳转换时间。

Abstract: Under the same computational condition and total impulse, lateral dispersion from 2-stage-thrust rocket or 3-stage-thrust rocket is analysed with detailed data- It can be concluded that the lateral dispersion for 2-stage-thrust rocket is less than that for 3-stage-thrust rocket.Furthermore, the optimum switch time at which the dispersion approaches minimum can be obtainedfrom calculation.
