| 摘 要： | 在案件现场众多特殊痕迹中,物体边缘痕迹是其中一种,它是由灰尘、水渍等物质在空间换位后形成的痕迹,此类痕迹没有严格的造痕体、承痕体之分。最为常见的边缘痕迹是由灰尘和水渍形成的。通过观察和分析灰尘和水渍形成的边缘痕迹,可分析留痕物体的基本形状,进而根据留痕特征进行同一认定。在检验过程中需要注意环境、留痕物质等对痕迹特征的影响。

| Abstract: | As one of the many special traces at the crime scene, edge trace, is composed of dust, water spots and other substances by spatial transposition with no strictly distinguishable objects to make and to bear traces. The most common edge trace is formed by dust and water spots. The basic shape of the object can be analyzed, and then identical authentication can be made according to the characteristics of traces by observing and analyzing edge trace formed by dust and water spots. In the inspection process, it should be noted that environment, trace substances and so on can have an effect on trace characteristics. |
