谈推断打击工具种类的方法

On Methods of Concluding Types of Striking Tool

物体表面被破坏的情况与工具的强度和形状有着重要的关系。根据物体表面的打击痕迹推断工具的种类,可以从多角度进行分析。垂直打击,留下的是工具打击面的完整轮廓;倾斜打击,留下的是工具打击面的一个部分。从痕迹的轮廓和反映出来的边数、夹角、痕迹中心点之间的距离等特征可以推断出工具打击面的形状。

The destroy level of material surface is strongly assosiated with the strength and shape of the tool. We can conclude types of the tool in accordance with the striking traces of the material surface from various aspects ： vertically striking results in complete profile of the striking side ; aslant striking results in fragments of the striking side. Shapes of the striking side may be concluded from figures like the side number, edge angle, distance to central points of the evidence shown from the outline of the trace.
