| 摘 要： | 在空巷道中电磁波存在着截止频率，机车的存在改变了巷道的截面形状和尺寸，从而对电磁波的截止频率有一定的影响。将巷道看作波导，利用有限元法，分析了矩形巷道，半圆拱形巷道以及圆形巷道中机车高度对电磁波截止频率的影响。

| Abstract: | There exist cut-off frequencies of electromagnetic wave in a tunnel.Existence of the electric locomotive can change a section shape and size of the tunnel,resulting in certain effect on the cut-off frequencies of electromagnetic wave.Taking the tunnel as wave-guide,the finite element method was used to analyze a rectangular tunnel,semicircular arch tunnel and the effect of height of the electric locomotive on the cut-off frequencies of electromagnetic wave in the circular tunnel. |

| Keywords: | Electric locomotive Rectangular tunnel Semicircular tunnel Circular tunnel Cut-off frequency Finite element method |
