摘要：

背景：研究认为当生物组织的温度高于44 ℃时会发生热损伤，准确地预测烧伤范围，可以为烧伤的诊断和治疗提供很大帮助。
目的：建立皮肤组织热烧伤的数学模型，分析烧伤过程中的温度变化规律，预测其烧伤范围。
方法：建立皮肤有限元模型，对皮肤组织在烧伤过程中的温度场进行数值模拟，得出了皮肤组织的瞬态温度分布，同时用新鲜带皮猪肉进行了烧伤后温度测量实验，将数值计算结果与实验结果进行对比。
结果与结论：利用有限元法分析得出皮肤组织的温度分布情况，发现理论数值和实验数值温度变化趋势基本一致，但并未完全重合。提示该有限元模型可以用来预测皮肤组织的烧伤范围。

Abstract:

BACKGROUND: Researchers suggest that thermal damage happens when the temperature of biological tissues is over 44 ℃. Accurate analysis of burn range will facilitate diagnosis and therapy of skin burns.
OBJECTIVE: To establish the mathematical model of the skin tissues subjected to high temperature and to analyze heat transfer process, and then to predict the burn range of the skin.
METHODS: A finite element method was used to simulate the temperature field when the skin tissue was burned. And the relevant animal experiment was conducted to identify the mathematical model.
RESULTS AND CONCLUSION: The temperature field was obtained by using the finite element method and the variation tendency between the theoretical data and the experimental data were agreed, but they did not fully coincide. The scope of skin burn can be predicted by the present finite element method, and help to research the process of heat transfer.
