目前电生理实验的主要记录手段之一是示波器照相。在一系列的实验过程中,大量底片很容易发生混乱,因此对每一张照相底片进行编码是十分必要的。最近我们采用了改装后的小型计算器进行编码,即经济又实用,安装简单,操作方便,而且改装后的计算器仍保持原有的一切功能,可供实验室使 At present, one of the main means of recording electrophysiology experiments is oscilloscope photography. In a series of experiments, a large number of negatives are prone to confusion, so it is necessary to encode every photographic negative. Recently, we have adopted a modified small calculator for coding, that is economical and practical, easy to install, easy to operate, and the modified calculator still retains all the original features for laboratory use
