摘要
目的研究92式手枪射击距离与射击残留物分布密度的相关性,为射击距离的推断提供依据。方法选择92式手枪,在带皮的猪肉上覆盖白色棉布,设计了0m,0.1m,0.2m,0.5m,1.0m,1.5m,3.0m,5.0m,10m,15.0m,20.0m,25.0m共12个距离进行射击,提取白棉布上的弹孔圆周和距弹孔2cm的圆周上的射击残留物,利用扫描电镜/能谱仪对不同射击距离遗留在白棉布上的射击残留物进行检验。结果白棉布上射击残留物分布密度与射击距离呈负相关的关系。结论根据棉布上射击残留物的分布密度,能够推断射击距离,对涉枪案件中射击距离的判断有一定的参考价值。
Objective To explore the relation of gunshot distance and distribution of gunshot residues of 92-pistol. Method The white cotton fabric placed on a piece of pork was fired at 0 m, 0.1 m, 0.2 m, 0.5 m, 1.0 m, 1.5 m, 3.0 m, 5.0 m, 10 m, 15.0 m, 20.0 m, 25.0 m distance with 92-pistol. The gunshot residues around bullet hole on the white cotton fabric were investigated by SEM/EDS. Results There was a negative correlation between the density of gunshot residues and the gunshot distance. Conclusion The result is very useful to estimate the firing range in the gunshot cases.
