摘　　要：舌体的三维温度场的建立可直观反映全舌空间温度的分布情况,能够深层次分析全舌的传热特性。本文选择猪舌为实验研究对象,建构舌体真实血管分布的物理模型为计算机可识别的数字模型,在此基础上用有限元方法对舌体三维温度场的数值模拟做了初步探索。讨论了血管形状分布,血液灌注率,代谢热与生物体三维温度场变化规律的相关性。Developing 3-D temperature field of tongue can directly reflect spatial temperature distribution of the whole tongue, as well as analyze its heat transfer characteristic further. In this paper, porcine tongue was chosen as experimental object to develop the realistic vessel physical model, then transfer it to numerical model which computer can identify. In the end finite element method was chosen to simulate 3-D temperature of tongue as a preliminary study. The correlation of vessel distribution, blood perfusion rate and metabolic heat generation to biological 3-D temperature distribution was also discussed.
