摘　　要：为确定不同病症人舌舌面温度分布出现差异的原因,对影响舌体传热的参数进行单因素分析。首先根据实验结果和理论分析,选定研究参数为:舌面相对湿度、舌体代谢热、根血管入口位置、根血管直径、血液流速、血管树分支指数。然后利用人舌温度场数学模型,分析每个参数对舌面温度数值和分布规律的影响。结果表明:上述参数都对舌面温度的数值有影响;根血管入口位置、舌体代谢热、舌面相对湿度对温度分布规律有明显影响。The parameters which can influence heat transfer of tongue were analyzed in order to reveal the reason why the tongue temperature fields of people with different diseases are distinct.Firstly,the research parameters were determined by experiment results,including the reference humidity of tongue surface,metabolic heat of tongue tissue,the entrance position of root vessel,the diameter of root vessel,the blood flow rate,and the bifurcation exponent of vascular tree.Then the effect of each parameter on the value and the distributing rule of tongue temperature field was analyzed by using a mathematic model of lingual temperature field.Results show that all these parameters have effects on the temperature value of tongue.The reference humidity of tongue surface,the metabolic heat of tongue tissue and the entrance position of root vessel are distinct influences on the distributing rule of tongue temperature.
