摘　　要：目的研究猪皮损伤创口内微量物证提取检验方法,探索致伤工具残留物成分认定方法。方法用锤子打击猪皮,并用滤纸、棉花棒提取损伤创口的微量物质,应用扫描电镜X射线能谱技术检验,确定致伤工具成分。结果猪皮残留微小颗粒可以定量地与锤子成分进行比对检验,扫描电镜X射线能谱技术可对微小颗粒成分分析。结论该方法可以作为致伤工具成分认定的参考,对致伤工具推断具有现实意义。Particles in skin traumatized by hammer were collected with filter paper and cotton swab. The elements of the particles were analyzed and compared with the components of the hammer by using SEM/EDS. The results indicated that metal particles in traumatized skin can be collected with both filter paper method and cotton swab method and determined with SEM/ EDS.
