在生理学研究中,在体内同时记录用极谱法测得的化学元素的含量和用电子测量法测得的生理电信号是一个十分诱人的方法。因为这样可以校正体内某区域的某种物质的浓度,并能实时观察结果。遗憾的是两个系统连在一起操作时,电生理信号会受到很强的电干扰,这是由于极谱产生相当大的刺激电流,通过共地回路影响电生理信号。本文所介绍的方法表明,当极谱和它对应的电极通过光电耦合时,可
In physiological studies, it is a very attractive method to record simultaneously the content of chemical elements measured by polarography and the physiological signal measured by electronic measurement in vivo. Because this can be a body area calibration of a substance concentration, and real-time observation of the results. Unfortunately, when the two systems are operated together, the electrophysiological signal is strongly electrically disturbed because of the considerable stimulation current produced by the polarography and the electrophysiological signal through the common ground loop. The method described in this article shows that when the polarogram and its corresponding electrode are photocoupled,
