摘　　要：本文论述了电偶源频率电磁测深中，利用比值视电阻率和相应阻抗相位进行联合反演的必要性和可能的应用前景及具体实施方法。理论模型和实际观测资料的反演试验表明这一联合反演是可行和有效的，且明显地优于视电阻率和阻抗相位的单参量反演。Abstract This paper deals with the necessity and possible prospects of utilizing ratio apparent resistivity and corresponding impedance phase to the performance of composite inversion in the frequency electromagnetic sounding of electric double source, and studies methods for practical application' Theoretical model and inversion test of observation data show that such composite inversion in feasible and effective, and is obviously superior to single-parameter inversion of apparent resistivity and impedance phase.
