摘要矩形巷道截面尺寸對電磁波的傳播特性有很大的影響。
Based on the radio waves propagation models of circular tunnels and rectangular tunnels , the relation between attenuation and conductivity is analyzed and the concept of conductivity breakpoint is presented
根據圓形巷道和矩形巷道的電波傳播模型，分析了電波衰減率和電導率的關系，并且提出了電導率斷點的概念。
When frequency slightly higher than cutoff , using perturbation method it is to know that tunnel wall wet make attenuation of electromagnetic wave lower not only in rectangular tunnel but also in circular tunnel
當頻率略高于隧道截止頻率時利用微擾法可知：不論是矩形隧道還是圓形隧道，隧道壁潮濕使電磁波的衰減率降低。
When frequency much higher than cutoff , using classical formulation method it is to know that tunnel wall wet make attenuation of electromagnetic wave increase in rectangular tunnel and make attenuation of other electromagnetic wave mode increase but te mode with tunnel wall permittivity
當頻率遠高于截止頻率時，利用傳統公式法可知：矩形隧道中隧道壁濕潤引起衰減增大；圓形隧道中e模式衰減率因電容率的增大而減小，其他各模式則因電容率的增大而增大。
The results show that in a rectangular tunnel with bigger dimension of the width , field strength of horizontal polarization mode is markedly higher than that of vertical polarization mode , influence of the height change on the field strength is stronger than that of the width change , and the difference of influences decreases with the increasing of frequency and transverse dimension
結果表明：在寬度尺寸大于高度尺寸的矩形巷道中，水平極化模式的場強明顯高于垂直極化模式，高度尺寸的變化對場強的影響比寬度尺寸的變化要大，這種影響差異隨頻率的增高和截面尺寸的增大而變小。
