6.A new inversion method is derived in the resistivity sounding based on Dar Zarrouk curves, with the similar character to Bostick inversion method in electromagnetic sounding,which transfers the sounding curve plotted the apparent resistivities as a function of the spacing of sounding configuration AB / 2 to the curve plotted the resistivities as a function of depth H. It is certified as a quick and correct inversion method by a lot of theoretical calculated results.
