人体创口工具残留物的扫描电镜能谱检验法

摘要

Purpose: To set up the method of examination of the trace of tool residuum on the body trauma. Method: Through setting up proper parameters, inspect the trace of suspect residuum attached on the body trauma by analyzing the X-rays spectrum of SEM through software of GSR (FEATURE). Results:Through the analysis of the component of the granules of the tool residuum left on the body trauma, the question of component analysis of the tool residuum on the body trauma can be comprehensively answered. It sets up the key theoretical and technical basis for the research on extrapolating the wound-lead tool on body trauma. The software of GSR ( FEATURE) is very important in setting up the research method for trace analysis in the field of forensic medicine.%本文通过设置合适的参数,使用扫描电镜X射线能谱GSR(即FEATURE)软件检验人体附着微小可疑残留物,借以形成人体致伤工具微量残留物检验方法,为人体损伤致伤物推断研究建立重要的技术方法.结果表明使用GSR(FEATURE)软件可定量检测到人体创口内微量工具残留物；通过对人体创伤工具残留物颗粒成分进行分析,可以全面解决人体残留致伤工具成份分析问题,为人体损伤致伤物推断研究建立关键理论技术基础;GSR(FEATURE)软件对于建立法医微量物证研究方法具有重要意义.
