| 摘 要： | “六四”式7.62mm手枪射击后会形成5种弹头痕迹和11种常见的弹壳痕迹。5种弹头的痕迹出现率和细微特征的稳定性各不相同,其中阳膛线、阴膛线的出现率最高,起末端痕和小线纹的稳定率最高。11种弹壳痕迹的出现率和稳定性也各不一样。分析弹头痕迹、弹壳痕迹的出现率、痕迹特征的稳定性以及差异形成原因,能帮助我们区分和认定有关枪支。

| Abstract: | The bullet of "6.4" pistol will form five kinds of bullet traces and eleven often-seen cartridge case traces after shooting.The emergence rate and stability of slight characteristics of the five kinds of bullet traces are different,among which yang and yin bore lines appear most and the stability of its starting and ending trace as well as little line trace is the highest.Meanwhile,The emergence rate and stability of the eleven kinds of cartridge case traces are also various.Analyzing the emergence rate and stability of bullet and cartridge case trace as well as their different causes can help us differentiate and determine various guns. |
