| 摘 要： | 分别采用抛物线导热模型和双曲型导热模型对有限厚度材料内部的热传导进行了研究，通过理论分析和数值计算，发现在不同导热模型下，材料内部的温度场分布有十分显著的差别，特别在双曲型导热模型下，材料内会出现过热或过冷的等非常规现象，这对于生物质传热和激光加工过程中温度的控制有重要意义。

| Abstract: | Parabolic and hyperbolic models were used to investigate the heat conduction in finite thickness materials separately.Theoretical and calculating results indicate that the temperature profile has great difference for different heat conduction models,especially when hyperbolic model is used,and there is unconventional phenomena of over_heat or over_cold in materials.It is very important for temperature control during biological heat transfer or laser process. |

| Keywords: | heat conduction temperature profile numerical simulation |
