%X According to the relationship between time and frequency,TEM sounding data can be transformed into plane-wave sounding data,for the purpose to process TEM data as MT.During the study of transformation from TEM diffusion field sounding data to plane-wave electromagnetic sounding data,it has been discovered that there exist distortions in early-time data because of using late-time calculating formula in all time delay and configuration.In this paper,the formula of late-time apperent resistivicy curve has been constructed.Theoretically,the late-time point of different configuration and geo-electric structure has been given.After a lot of calculation of models and theoretical analysis,according to different time-delay,survey configuration,geo-electric structure,a revised method of TEM early-time field data has been given.
