| 摘 要： | 目的利用环境控制扫描电镜/能谱仪（SEM/EDX）研究枪弹创射入口周围射击残留物与射击距离的关系,探讨其能否用于射击距离的判断。方法采用＂＂5.4＂＂式手枪分别在5、10、15、20、30、40、50、60、70、80、90、120cm处射击乳猪皮肤,利用SEM/EDX观察创口周围GSR的分布和成分,并建立回归方程。结果射击距离和GSR颗粒数量之间总体表现为直线关系,并建立了相应的回归方程。当射击距离为10~90cm时,用该方程推断射击距离效果较好。结论检测创口周围GSR可望用于判断“5.4”式手枪的射击距离。 |

| Abstract: | Objective To study the relationship between GSR and firing distance, and to discuss whether the relationship can be used to estimate the firing distance. MethodsShotting porkets with "5.4" hand gun at the firing distance of 5, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 120cm respectively, then observing the distributing and element of GSR with SEM/EDX and finally building the equation of regression. ResultsThe relationship between the quantity of GSR and firing distance is linear and the equation is built. When the firing distance is from 10 to 90cm, the result is preferably. ConclusionWe can estimate the "5.4"hand gun firing distance through testing GSR around gunshot wounds. |
