Applying combined method of quantitative analysis and qualitative analysis, on the basis of on ago research fruit, this paper firstly analyses main factors that affect the safe distance from friendly force to target for tank gun overhead firing systemically. Based on that, this paper builds math model of calculating the safe distance from friendly force to target separately aiming to the difference of tank gun overhead firing in plane and undulate terrain. At last, through applying Mathematica soft, this paper presents the safe distance from friendly force to target for a tank gun overhead firing used APFSDS, HEAT and HESH, combined qualitative analysis.

采用定量分析和定性分析相结合的方法，在以往研究成果的基础上，首先系统地分析并提出了影响坦克炮超越射击时友军至目标安全距离的主要因素；以此为基础，针对平坦地形和起伏地形上坦克炮超越射击的不同情况，分别建立了确定友军至目标安全距离的数学模型；最后通过运用Mathematica软件进行定量计算，并结合定性分析，提出了某型坦克炮使用尾翼稳定脱壳穿甲弹、空心装药破甲弹和杀伤爆破榴弹进行超越射击时友军至目标的安全距离。
