以钢化玻璃物理特性为基础,全面分析不同类型物理钢化玻璃破裂后的裂纹形态,论述了不同作用方式下钢化玻璃的规律性裂纹形态。认定钢化玻璃自爆原因时,应摒弃传统硫化镍成因绝对论,其他杂质颗粒以及结构缺陷在成因中也占很大比例。判断钢化玻璃受冲击而破裂的作用方式及相关信息,必须首先确认玻璃的钢化类型,再结合裂纹及开裂点具体形态,才可以为案件的侦破提供正确的侦查方向。
Based on the physical properties of toughened glass, the crack shapes of different types of toughened glass are comprehensively analyzed. The regular crack morphology of toughened glass under different modes of action is discussed. Found that the cause of self-destruction of tempered glass should abandon the absolute theory of nickel sulfide causes, other impurities and structural defects in the genesis also accounted for a large proportion. To determine the mode of impact and rupture of toughened glass and relevant information, we must first confirm the type of toughened glass, combined with the specific form of crack and crack point, can the detection of the case to provide the correct direction of investigation.
