If the cross section area of the two branching ducts are different, the Included angle on the smaller branch duct against the extended center line is usually bigger.

若分枝管的截面积大小不同，则细支管与母管中心延长线间的夹角较大；

Four propagation models of diffraction, line-of-sight, scatting and duct are analyzed. The basic transmission loss for each of the models is calculated according to the ITU-R model and GZB model.

分析了电波的地波绕射传播、视距传播、散射传播和波导传播等四种传播模式，根据ITU - R和GZB建议的模型分别计算了各传播模式的基本传输损耗。
