根据皮肤改变推断死亡时问

Estimation of the Time Since Death Based on the Postmortem Changes of the Skin

死亡时间推断是法医学工作首要解决的基本任务，也是研究的热点和难点问题。传统方法主要是根据尸体现象、超生反应和胃内容物消化程度进行推断。皮肤是机体死亡后保存时间最久的组织之一，近年来的研究针对死后皮肤大体形态学、组织形态学、温度、电阻抗、生物力学特性的改变，为推测死亡时间提供了新的方法和思路。

Primary task of forensic medicine is the estimation of the time since death, which is of central importance and also a difficult point to elaborate in practice and theory. Traditional methods of determining the postmortem interval include examination of postmortem changes, supravital reaction and degree of stomach contents digestion of the body. Since the skin is the latest part to be breakdown when a cadaver decomposition processed, peoples investigated the gross, histologic, temperature, electric impedance, biomechanics characteristic changes of postmortem skin, and provide us some potential methods for estimation of postmortem interval.
