文中计算了两层分层地面的有效电参数,并分析了该有效参数随上下两层地面的实际电参数及上层厚度的变化规律。文中还计算了低频地波在不同的分层地面上传播的地波衰减因子曲线。由这些计算可以得出结论:由于地面的分层低频地波衰减因子的幅度|Wg|随距离的变化规律与均匀地面时不同,若用测量地波场强和相位(|Wg|、ArgWg)来推算地面的等效导电率参数、对于同样的路径情况会得到两种不同的等效导电率参数值。
In this paper, the effective electric parameters of two layers of stratified ground are calculated, and the variation rules of the effective parameters with the upper and lower two floors of the actual electric parameters and the thickness of upper strata are analyzed. The paper also calculates the ground wave attenuation factor curve of low frequency ground wave propagation on different stratified ground. From these calculations it can be concluded that the magnitude | Wg | of the attenuation factor of the low frequency ground wave due to the stratification of the ground is different from that of the uniform ground. If the ground wave intensity and phase (| Wg |, ArgWg) To calculate the equivalent conductivity parameters of the ground, two different equivalent conductivity values are obtained for the same path condition.
