摘　　要：在已推导的新数学模型基础上，针对法医实践中遇到的数学问题，把数学理论推导与动物和尸体实验相结合，辨识模型参数，建立了推算死亡时间的新方法．在微机上利用组内非正常死亡的直肠温度数据推断死亡时间，其误差较小，参照文献数据，本法略优于国内同类研究报导的方法。Based on the new inferred mathematical model, mathematical inference was combined with experiments of animals and corpses to identify the model parameters in Forensic medicine problem and to establish a new method of inferring the time of death. The error was small when the time of death was inferred by the data of the rectal temperature of abnormal death in arrags in computer. Referring to the reference data, the method in this paper was superior to others reported in the same research. The parctical application was still to be studied.
