摘　　要：根据12条地波路径实测得到的地波二次相位因子和基准场强的数据,探讨了在处理地波传播问题时等效地球半径系数α的取值问题。分析表明:在我国内陆,α选用4/3较宜。The selection of the value of the Earth equivalent radius coefficient in dealing with ground-wave propagation is investigated based on the secondary phase factors and datum field intensity obtained from the observations for 12 propagation paths.Analyses indicate that 3/4 is the reasonable choice of the equivalent Earth radiu s coefficient for ground-wave propagation in China’s inland.
