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
根据圆形巷道和矩形巷道的电波传播模型，分析了电波衰减率和电导率的关系，并且提出了电导率断点的概念。
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
当频率略高于隧道截止频率时利用微扰法可知：不论是矩形隧道还是圆形隧道，隧道壁潮湿使电磁波的衰减率降低。
To minimize worsening of traffic congestion and taking environmental and visual concerns into consideration , most mrt system routes in metropolitan areas are underground . except for those stations and crossovers where wide ranging areas are involved , the tunnel boring machine is usually applied . conventional tunnel boring was first adopted in 1818 in london , but at that time was only used on a one - line circular tunnel basis
