摘要
痕迹特征显示,导针在凹坑底面的垂直印压痕迹、导针与凹坑壁的斜向碰撞擦划线条痕迹、导针与凹坑侧壁的横向擦划痕迹,可作为判定圆柱形钥匙是否被复制依据的痕迹;齿间柱面上的复制痕迹、钥匙体夹持面痕迹可作为判定圆柱形钥匙是否被复制的参考辅助痕迹。
The trace features show that the guide pin＇s vertical pressing traces,the oblique line traces caused by the scratches between guide pin and cratered side and the transverse traces caused by the scratches between guide pin and cratered side could be used to determine whether the cylindrical key has been duplicated or not,and the duplicating traces on the interdental cylinder and the traces on the key body clamping surface could be used to determine whether the cylindrical key has been duplicated or not.
