摘　　要：目的 建立推断制式霰弹猎枪射击距离的数学计算公式和方法。方法 选用国产制式12号及16号猎枪,配用1号及3号猎枪弹,以1至12m距离射击实验靶纸,获得霰弹分布图形360例,将图形测量数据与实验距离进行数学理论分析。结果 建立6种不同枪弹种类推断射击距离d的计算公式,分别为12-1型(缩口)ss=-0.2+0.44d;12-1型(无缩口)ss=-0.94+0.63d;12-3型(缩口)ss=-0.59+0.52d;12-3型(无缩口)ss=-0.36+0.34d;16-1型s=-0.37+0.30d;16-3型s=-0.16+0.23d,并用Visual Basic5.0软件编制通用程序汇总软件。结论 本研究建立的方法简单实用,误差较小,可以用于推断制式猎枪的射击距离。Objective To provide a mathematical formula and method for estimating the distance of shooting by uniform shotgun. Method 360 distribution graphs of canister were made on experimental target paper by shooting with No. 12 and No. 16 uniform shotgun (made in China), using No. 1 and No.3 pellets at the distance of shooting from 1m to 12m. The data of graph measuring and experimental distance were analyzed by mathematic theory. Results Six different types of mathematic formula were obtained for deduce the distance of shooting. They are: 12-1 type (choke) ss= -0.2 + 0.44d; 12- 1 type (no choke) ss= -0.94 + 0.63d; 12-3 type (choke) ss= -0.59 + 0.52d; 12-3 type (no choke) ss= -0.36 + 0.34d; 16-1 types= -0.37 + 0.30d; 16-3types= -0.16 + 0.23d. General software was made using Visual Basic 5.0 computer program. Conclusion This method can be used to deduce the distance of uniform shotgun shooting with little error.
