Based on the physics of the "shock wave" interpretation,the shock wave theory is applied to the formation of the two marks: the supersonic flight of one bullet in the air and the product of explosive expansion in the air.To analyze the role of shock wave%基于物理学对"冲击波"的解释,文中将冲击波理论用于解释两种痕迹的形成:一是子弹在空气中的超音速飞行,二是炸药爆炸产物在空气中的膨胀。通过冲击波的痕迹分析,可以判断出子弹的飞行速度或是炸药量的多少,对侦破此类案件具有重大意义。
