In combination with the result, the author points out that radiowave attenuations in roadway is mainly by wave refraction and reflection rather than wall absorption.
结合理论分析，指出无线电波在井巷中引起电波衰减的主要原因是波的折射与反射，而不是巷壁的吸收。

And in electromagnetic theory the dielectric of sea water is not constant. After the reflection from ocean surfaces, the amplitude and phase of radiowave can be both changed.
