摘　　要：在各类案件中,纺织物上刀具砍、切等破坏痕迹经常出现。对这些痕迹进行科学分析可以正确判断出作案刀具的种类特征、个别特征,形成痕迹的方式以及因角度、纺织物质地的不同所造成的痕迹差异,从而为公安机关侦破案件提供明确的方向,提高破案效率。本文以棉纺织物为实验样本,综合刀具成痕时的角度、方向和力度等因素,探索菜刀在破坏纺织物时的成痕特点,由此找出痕迹规律,以便为公安实战提供有力帮助。The traces left by knives are commonly seen in textiles in various cases. It will undoubtedly help investigators to tackle cases if they can make right decision about the type and individual characteristics of knives, trace-forming way, and trace differences due to different kinds of textiles. Taking cotton fabric as samples, the paper explores the characteristics of traces cut by kitchen knives in textiles together with the angle, direction and force when cutting is made so as to find the principles of traces, which might be helpful in investigation.
