一、引言在电工程中,有时会遇到脉冲在不同截面的传输线中的传播问题。我们所研制的流光室需要提供600kV幅值、10ns脉宽的高压脉冲,这种高压脉冲通过传输由截面为两个同心圆的Blmlein线加到外截面为矩形、中心电极截面为哑铃状的室本体,室本 I. INTRODUCTION In electrical engineering, the problem of the propagation of impulses in transmission lines of different cross sections is sometimes encountered. The streamer chamber we developed needs to provide a high voltage pulse of 600 kV amplitude and 10 ns pulse width. This high voltage pulse is transmitted through a Blmlein line with two concentric sections in cross section to a rectangular outer section with a central dumbbell section Body, Room this
