| 摘 要： | 本文叙述的脉冲波形微分变换,是一种专门用于某些脉冲波形在t—u坐标系和u-du/dt坐标系之间实现数学变换的方法。其目的主要在于准确求出不规则电脉冲随幅度变化的速率变化。文中介绍了几种常用的数学函数的微分变换,以及实现这种变换所用的微分器和实验装置,在双踪示波器屏幕上能够显示出速率变化图形。这种图形,在医学上对研究肌肉和神经电脉冲是非常有用的。

| Abstract: | The differential transform of pulse waves described in this paper is a special method by which mathe matical transforms of certain functions between a coordinae system in v, t and the present coordinate system in v, dv/dt can be realized. The purpose of the transform is mainly to evaluate exactly the rate changes of irregular spikes with changes in potential. Differential transforms of several common functions are presented, as well as the differentiator designed for this purpose and the laboratory installation. A rate change pattern is shaped on the screenof a dual-beam oscilloscope by means of the differentiator, which is very useful for researching muscle or nerve spikes in medical science. |
