人体耳穴电特性3参数模型

A THREEPARAMETER MODEL OF THE ELECTRICCHARACTERISTIC OF HUMAN AURICULAR POINTS

用微机实验系统测定耳穴电参数．根据耳穴瞬态响曲线，设计由等效电阻、电容和电位构成的三参数模型（ＴＰＭ），模拟耳穴电特性．模拟测量和数学分析所得响应函数ｕｅ（ｔ）与耳穴响应ｕａ（ｔ）符合较好．耳穴与ＴＰＭ实验数据配对比较无显著差异，ｐ＞０．０５．ＴＰＭ能较好地反应与描述耳穴系统．这为深入研究耳穴电特性及其应用提供了重要的基础和一种新的方法．

We can measure electric parameters of human auricular points accurately and recognize the system with a microcomputer measuring system. According to experiment results, we have designed a ThreeParameter Model (TPM) consisting of the equivalent resistance R, capacitance C and body surface potential E, and carried mathematic analysis. The response ue(t) was obtained by calculation and simulation measurement, which conforms to experiment curve ua(t) of the auricular points. After the statistical processing of the two groups of the experiment data, the results show: there is no notable difference, P>0.05 between acupoint and TPM. So TPM can describe acupoint system. The research provides a theory and new method to study and apply electric characteristics of the auricular points. It is important to the development of the traditional Chinese acupucturology.
