摘　　要：奥运射击比赛的子弹都是由参赛队伍自行准备的,对于比赛用子弹的挑选,则成了一个很重要的环节,甚至可以说就是正式比赛的组成部分。之前我们讨论了一种使用中子照相的无损检测方法,可以准确快速地帮助教练员挑选比赛或训练用子弹。在中子照相的基础上,进一步对英国爱莱牌子弹、拉普阿子弹与国产三角牌子弹进行实弹抽样试射研究,对比3种品牌子弹在装药量、子弹射出时的速度以及弹着点离散情况的差异,最终选择出奥运训练和比赛用的高质量用弹。The shooting match ammunition is prepared by teams themselves in Olympic Games.The selection of the bullets has become a very important link.The previous article described a non-destructive testing method,which can help the coaches to choose match bullets quickly and accurately.Combining with the results of non-destructive testing,this paper carried out a sample test between the brand of ELEY and Triangle,compared the differences of these brands bullets in speed of bullets,charge volume,as well as targeting dispersion.Finally,a kind of high quality ammunition was selected for the shooting competition in Olympic Games.
