Measurement of corpse temperature is mainly used for estimation of early postmortem interval, and rectal temperature is often used as a representative of body's core temperature in actual work because it is simple, quick and non-invasive. At present, the rectal temperature postmortem interval estimation method internationally accepted and widely used is HENSSGE's nomogram method, while many domestic scholars also deduced their own regression equations through a large number of case data. Estimation of postmortem interval based on rectal temperature still needs further study. The nomogram method needs to be optimized and extended, and quantification of its influencing factors needs to be dealt with more scientifically. There is still a lack of consensus on the probability and duration of the temperature plateau. There is no clear understanding of the probability and extent of the change in initial temperature caused by various causes. New methods and ideas enrich methodological research, but it still lacks systemicity and practicality. This article reviews the researches on estimation of postmortem interval based on rectal temperature in order to summarize the current situation of previous researches and seek new breakthrough points. Because the decline of body temperature can be easily influenced by many factors in vitro and vivo, and the influencing factors in different regions vary greatly, regionalization research and application may be a practical exploration to improve the accuracy of postmortem interval determination.
尸体温度测量主要用于推断早期死后间隔时间，在实际工作中，直肠温度常被用作机体核心温度的代表，因为其测量方法简便、快速且无创。目前，国际上公认且广泛应用的基于直肠温度推断死后间隔时间的方法是亨斯格（HENSSGE）列线图法，国内也有诸多学者通过大量案例数据推导出自家的回归方程。基于直肠温度推断死后间隔时间仍有待深入研究。列线图法需进一步优化与拓展，其影响因素的量化处理也需更具科学性。在温度平台期的出现概率及持续时长方面，目前仍未达成共识。对于各种原因导致的初始温度变化概率及幅度，尚无清晰认识。新方法与新思路丰富了方法学研究内容，但仍缺乏系统性与实用性。本文对基于直肠温度推断死后间隔时间的研究进行综述，旨在总结既往研究现状并探寻新的突破点。鉴于体温下降在体内外易受多种因素影响，且不同区域的影响因素差异较大，开展区域化研究与应用或许是提高死后间隔时间判定准确性的一种切实探索。
