摘要： 在法医学实践中,死亡经历时间的推断具有重要的实践价值,但其准确推断却一直是法医学实践的难题,因而也一直是法医学研究的热点。法医DNA技术是近年来发展起来的在分子水平进行死亡时间推断的新技术、新方法,同传统方法相比,具有很大的优势,本文对该技术提出的背景、发展、优缺点以及发展前景进行综述,着重对DNA含量变化与其相关性的研究进展进行讨论。

Abstract: Determination of postmortem interval(PMI) is one of the most valuable subjects in forensic practice.It,however,is often very difficult to accurately determine the PMI in daily practice.Forensic DNA technology has recently been used to estimate the PMI.It has certain advantage to traditional methods.This article reviews this technology with respect to its invention,development,advantage,disadvantage,and potential future applications with emphasis on correlation of DNA degradation and PMI.

Key words: postmortem interval, autolysis, DNA degradation, forensic medicine
