Postmortem interval （PMI） estimation is one of the most important and difficult academic tasks in forensic sciences. Due to the influence of the corpse itself and the water environment, corpses in water have unique corruption phenomenon and laws. Based on the experience of traditional PMI studies of corpses on land, forensic practitioners across the world have proposed a variety of practical methods for estimating postmortem submersion interval （PMSI）. This paper summarizes the literatures related to PMSI in recent years, and introduces methods to infer PMSI according to the phenomenon of corpses, the development of insects, the succession pattern of aquatic organisms, and the changes of other physical and chemical indexes of corpses, in order to provide some reference for the study of PMSI of corpses in water.
题目: 水中尸体死后淹没时间推断研究进展.
摘要: 死亡时间推断是法庭科学领域的重要研究内容和颇具难度的学术问题。由于受到尸体自身和水体环境的影响，尸体在水中具有独特的腐败现象和规律。世界各国法医工作者在陆地尸体死亡时间推断方法的基础上，对水中尸体死后淹没时间（postmortem submersion interval，PMSI）的推断提出了多种实用性较强的方法。本文对近年来水中尸体PMSI推断的相关文献进行了总结，介绍了依据尸体现象、昆虫发育情况、水生生物演替规律和尸体其他理化指标变化推断水中尸体PMSI的方法，希望对水中尸体PMSI推断的研究提供一定参考。.
