| 摘 要： | 为了充分利用现场遗留的锯路波痕迹,推断作案用锯的种类,笔者用木锯制作了大量带有锯路波的锯痕,并对实验样本进行分析测量,采用统计学中二独立样本的t检验方法对断面形态与锯齿组合的关系进行分析,找出了锯路波波纹方向与进锯方向夹角和锯齿角度的关系、进锯方向上的波距与同侧齿距的关系,为工具痕迹的锯痕检验提供参考。

| Abstract: | Plentiful kerfs samples with route waves are made by wood saw in order to make full use of kerfs left on crime scenes and deduce the type of crime saw.All these samples are analyzed and measured.The relation between cross section pattern and the combination of saw teeth is examined by T test statistical method.Relations among wave direction of derfs route,saw entering angle and saw tooth angle,and relation between wave distances of saw entering direction and tooth distance on same side are confirmed.This article provides a reference for kerfs examination. |

| Keywords: | kerfs kerfs route wave T test |
