前言在针灸

针麻原理的研究中

体表皮肤电阻(确切地说是阻抗)的测定是一个重要的手段。由于人体属于离子导电

皮肤电阻的大小与细胞膜的离子通透性直接有关

也与测量时

所施的电流性质有关。用直流测量时

由于组织的极化现象

阻值与电流的极性、强弱和时间有关

是一个变In the research of acupuncture treatment and acupuncture anesthesia

measuring the impedance ofthe skin is an important approach.In order to maintain the original state of the skin and to prevent distortion caused by measuringcurrent

a low level A.C.current skin impedance meter was used.Two different kinds of high freque-ncy and low frequency instruments are available

for measnring impedance of different zones.The feature

working principle

making and operation of these two instruments are introduced inthis report.
