摘要：

本文通过高频信号在铁路轨道上的试验说明了高频信号的基本特性。铁路轨道信号由于车轮与钢轨的接触不良而引起故障,特别是支线和不经常使用的线路由于铁锈和刹车闸瓦的不导电性,从而引起信号故障,为了解决此问题,我们利用高频信号的特性,在铁轨上做了大量试验,从而说明了高频信号的许多特有性质。

Abstract: The article specifies the high-frequency signal's character by the test of the high-frequency signal which is transmitted on the railway.The wheel of the train and the rail sometimes are in bad contact, and then the original signal doesn't work well. Accidents occur on the railway which is not often used.The causation is that the resistance is too high between the wheel and the rail.It is caused by the rust and other things.To resolve the problem, we have done a lot of tests about the high-frequency signal's transmission on the rail.The result demonstrated the character of the high-frequency signal.

Keywords: High-frequency; Impedance matching; Geometry parameter; Transmission
