摘　　要：已有的经络定位方法都是定性或半定量的,而经络实质的研究需要一种定量的方法来实现经络的准确定位。将低频方波脉冲注入人体手掌的穴位,利用生物电放大器采集前臂一些部位的脉冲信号。根据经络的低阻抗特性,响应信号的大小与阻抗成反比。用Fourier变换和小波分析方法对采集到的实验数据进行分析处理,确定前臂响应信号的最大点,也即阻抗最小点,该点应在经络上。连接阻抗最小点,在前臂皮肤上可以形成一条线。研究表明,这种方法得到的连线与传统中医对经络的位置的描述一致。此研究结果为中医经络的研究提供了一种新的研究手段。All of the meridian location methods are qualitative or half-quantitative at present time. while meridian essence reserch need an exact quantitative location method. Infused square-wave into a point on the palm, and measured the electric signals of several parts at the forearm. Acorrding to the characteristic of meridians resistance, the response signals are inversely proportional to resistances. Processed the data which gained from the bioelectricity amplifier with Fourier transform and wavelet analysis, and found out the maximum response points with minimum resistances which should be the meridian points. These points constitute a line and further study has some similarity with the TCM. This research raises a new method for TCM studying.
