Evaporation ducts, or tropospheric ducts in general, can guide radio waves to distances far beyond the horizon with less attenuation, and then severely impair some certain radio wave system. 以蒸发波导为代表的对流层大气波导传播,可使电波在较小的衰减下沿波导传播得很远,从而严重影响合适的无线电系统。
Atmospheric duct can guide radio waves to distances far beyond the horizon with less attenuation, which will have a significant impact on the spread of radio signals. 大气波导可以使电磁波陷获在波导层结内实现超视距传播,将影响在其中传播的无线电信号。
