92式手枪与警用转轮手枪射击颅骨模型的入出口形态比较
Morphological Comparison of the Entrance and Exit on Simulated Skull Shot by QSZ92 Pistol and Police Revolver
摘要
Abstract
Objective To identify the type of guns and shooting distance by comparing the morphological differences of the entrance and exit on simulated human skull shot with QSZ92 pistol and police revolver. Methods Simulated human skulls were shot from the same distance by the above indicated two pistols with 9mm bullets. Results When shooting at a 2.5-meter distance, QSZ92 can make the hardness-strong skull model being shattered. But for the hardness-moderate skull model, no shattering occurred by the two indicated guns to operate under same condition. The size and shape of entrance made by the two pistols were similar yet smaller than those of their each respective exit. Whereas, for the exit, the QSZ92 made a larger one than the revolver, causing the local outer plate of skull model to crack into a width-smaller inclining plane and producing more skull fragments to burst apart and fall. Conclusion By observing the shape of bullet holes on the simulated human skull model and comparing the bullet-shooting entrance and exit, QSZ92 can be distinguished from the revolver. Besides, the materials and method used here can basically meet Some needs for investigative experiment of gunshot wound formation on skull.关键词
