| 摘 要： | 研究了将正比计数管等效为电流源后,应用时域分析中常用的卷积积分的方法,分析含正比计数管的网络的输出电压.此法不但有利于通过网络分析的概念理解这一物理过程,而且便于计算正比计数管的输出电压或电流.所得的输出电压的表达式与应用其他方法所得出的结果相同,因此可根据输出电压的波形与电路时间常数的关系,选择时间常数以确定输出脉冲宽度,使正比计数管适用于不同的计数率.

| Abstract: | This paper studies on the convolution integral which is often used in time domain analysis through equivalent transforming proportional counter tube to current source, and analyzes output voltage of network containing proportional counter tube. This method not only comprehends network analytical method more easily but also calculates the voltage and current of the proportional counter tube more conveniently. Because the formula of output voltage is the same as the one using other methods,the pulse width can be ascertained by choosing time constant based on the relation between voltage and current, and the proportional counter tube can be applied to different count ratio. |
