Abstract: A convenient and fast numerical calculation method of alltime apparent resistivity for the transient electromagnetic method-inverse spline interpolation method has been developed. Several conversion examples, from induced electromotive force through centralloop TEM2.5D forward program to apparent resistivity, illustrate the feasibleness of inverse spline method. At the same time, the method has also laid the foundations of initial model definition in TEM automatic inversion.

Key words: transient electromagnetic method, alltime apparent resistivity, inverse spline interpolation
