When electrical parameter is changd by wet tunnel wall , electromagnetic wave propagation attenuation will vary
摘要矿井隧道壁湿润会引起电参数改变，从而使电磁波传播衰减率发生变化。
Moreover , although the diversity degree is limited , the interference level is closed to ideal case ( ie . , signal can received by all base stations ) and then capacity closed to isolated cell because of propagation attenuation especially in lower shadowing conditions
此外，由于信号固有的传播衰落，虽然分集度受限，但其基站所受干扰水平接近理想情形(移动台信号被所有基站接收) ，进而容量接近孤立蜂窝的容量。
Since there are only few papers about the topic , the simulating result have no alternative but to compare with the data of the upper inhomogeneous terrain . the similar trend is found for the two results , and larger propagation attenuation will follow the higher frequency or larger conductivity of the medium
由于有关覆盖层传播方面的文献资料几乎没有，所以只能把结果与地表均匀岩层的数据进行比较，结果表明平面波法和通信公式法计算得出的结果完全一致，并与在地表均匀岩层传播结果趋势类似，而且随着频率的增高或导电率的增大，传播衰减也增大。
