首次将跳弹痕迹的量化特征引入枪击跳弹分析,在不同弹道入射角条件下,系统地研究了钢板上跳弹点痕迹、弹头跳弹痕迹的尺寸、形态特征及其变化规律,提出了基于跳弹点痕迹、弹头跳弹痕迹的枪击现场重建技术。实验以92式9毫米手枪射击钢板为例,研究结果表明:在同一弹道入射角下,跳弹点痕迹、弹头跳弹痕迹均特征一致、稳定性高;在不同弹道入射角下,两种跳弹痕迹均差异明显,弹道分辨力高。因此,两种跳弹痕迹可以相互印证、可靠地重建枪击跳弹现场。
For the first time, the quantitative characteristics of bomb trajectory were introduced into the shoot-jump bomb analysis. Under the condition of different ballistic incidence angles, the trajectory characteristics of the jumping point and the trajectory of the bullet were studied systematically. Jump jump marks, bullet jump bomb marks the scene reconstruction techniques. The experiment takes the 9-mm 9-mm pistol shooting steel plate as an example. The results show that the trajectory of the jumping point and the trajectory of the bullet are consistent and stable under the same ballistic incident angle. The two jumps Bullet traces are significant differences, high ballistic resolution. As a result, the two types of jumping bombs can confirm each other and reliably rebuild the shooting bombshell scene.
