枪弹创前置物射入口形态学的实验研究

为建立前置物射入口与典型射入口的检验鉴别方法，使用国产54式7.62mm口径手枪及56式7．62mm口径半自动步枪，以3m的距离射击约克夏种白猪义3只，同时以各种玻璃、木板。汽车门、动物躯干等物质作为中间障碍物，制成前置物射入口36例，并与对照组6例射入口进行对比观察。结果显示，前置物射入口较典型射入口增大，撕裂，创线挫伤增宽，创周出现卫星创或假点彩，创道内异物及弹头严重变形。此检验诊断方法有助于法医在实际检验中对射击距离的判断和对现场环境的分析。

Experimental morphological study on shored entry wounds by gunshot

For the purpose of identifying the gunshot shored entry wound from the typical entry wound, 36 shored entry wounds were made on 13 Yorkshine plgs by shooting with 7. 62mm pistol type 54 and 7. 62mm semiautomatic rifle type 56 at a distance of 3m using the various glass, boards, automobile doors and animal trunks as the intermediate target, 6 entry wounds without the intermediate target were made as control. The results showed that shored entry wounds had many characters such as the large, with avulstion, wide abrasion margin, accompanied by the formation of satellite wounds or mimic gunpowder stippling around wound, foreign bodies in the wound canal as well as deformed bullet. This study provides a method for identifying the gunsh0t phored entry wound and estimating the distance of shooting and scence environment.
