摘　　要：等效地球半径的使用可大大简化电波在大气中传播时折射效应的复杂运算,因此在实际工程中获得广泛应用.针对近年来许多学者对等效地球半径的定义和应用范围的争论,通过对在真实地球和等效地球系下几个参量的对应关系的分析和讨论,给出了等效地球半径的等效性和局限性,以便在实际工作中正确应用.The refraction effect complex operation can be greatly simplified by using equivalent earths radius; therefore it is widely available in the actual project. In view of the argument to the definition and the application scope about equivalent earth＇s radius in recent years, the paper gives the analysis and discussion about several parameters corresponding relations in the real earth and the equivalent earth, then gives the equivalency and limitations of equivalent earth＇s radius in order to apply correctly in practical work.
