| 摘 要： | 目的:研究枪弹射入门周围射击残留物(GsR)与射击距离的关系,探讨其能否用于射击距离的判断.方法采用"7.9"式轻型冲锋枪分别在5cm、loom、15cm、20cm、30cm、40cm、50cm、70cm、80cm、90cm、120cm、120cm处射击乳猪,用SEM/EDX观察创口周围GSR的分布和成分,建立回归方程.结果射击距离和GSR颗粒数量之间总体表现为直线关系.结论根据创口周围GSR可以判断"7.9"式轻型冲锋枪的射击距离.

| Abstract: | Objective:Uo study the relationship between GSR and firing distance,and to discuss the possibility of estimating firing distance with GSR.Meth- ods:Porkets was shot with"7.9"mini submachine gun at the firing distance of 5em,10cm,15cm,20cm,30cm,40cm,50cm,60cm,70cm,80cm,90cm, 120cm respectively,then observed the distributing and element of GSR with SEM/EDX and found the equation of regression.Results:the correlativity between GSR and firing distance was linear equation.Conclusion we can estimate firing distance of"7.9"mini submachine gun by GSRaround Gunshot Wounds. |
