摘　　要：射击比赛一直以来都是奥林匹克运动会的正式项目,该项目对枪械和子弹的物理尺寸都有严格的规定。在射击比赛中,子弹的火药装填量是影响运动赛成绩的重要因素之一,如何对其进行无损检测,是各个射击队长期以来迫切期盼解决而未能解决的难题。为保证中国国家射击队所用子弹的质量,在对多种无损测量方法对比之后,使用X线和中子照相2种方法,分别对发令枪子弹、奥运射击子弹和几种装有不同类型火药的子弹做了对比测量,有效地提高子弹的可信度。最后对测量结果进行了理论对比分析,总结得出子弹火药含量无损检测的可行方法。In order to ensure the quality of the bullets,both X-ray and neutron imaging technique were selected for the bullet detection after comparing and analyzing many kinds of non-destructive methods.The samples,including starting gun bullets,pistol bullets and the bullets fitted with different kinds of powder,were detected respectively with the above methods.Then,the testing results were theoretically analyzed,and the practicability method of bullet detection was provided.
