摘　　要：目的对人体骨骼上刀痕进行致伤工具同一认定的检验和研究。方法用同一把菜刀的相同部位分别砍击骨骼与新鲜灌木,通过对骨骼上刀痕进行组织学处理以显现致伤工具的痕迹,并使用比对显微镜将骨骼与灌木上的砍痕进行比对,分析骨质断面的痕迹特征。结果菜刀在骨骼上形成的砍切痕迹线条与比对样本的砍切痕迹线条可以完全拼接。结论显微镜下可直观、清晰地观察到致伤工具在骨骼上留下的痕迹,为致伤工具的推断提供了新的方法。Objective The injury instruments were identified and studied according to the cleaver traces on bone.Methods The bone and fresh shrub branches were cut with the same part of the same cleaver respectively.To visualize the traces on the bone by histological processing and to match the traces on bone and branch by the comparison microscope.Then to analyze the character of traces on the bone.Results Cutting-line traces made by cleaver on the bone can be fully matched with those in the shrub branch sample.Conclusion Cleaver traces on the bone can be displayed clearly and shown at micro level.It will provide a new method for the identification of suspected weapon.
