Abstract：According to expression of field in half-infinite homogeneous media,the paper introduced the basic characters defined by all-time apparent resistivity of transient electromagnetic method (TEM) for several AB-s configuration,and discussed solving methods.Especially,the paper introduced a concept of "pseudo-all-time apparent resistivity"based on inductive electromotive force so that solved the problems such as uniqueness and existence of the solution of pseudo-all-time apparent resistivity.The pseudo-all-time apparent resistivity can better continuously and straightforwardly reflect the vertical conductive variation character of 1-D conducting layer,which has an important meaning for qualitative interpretation of transient electromagnetic data and lays the foundation for 1-D inversion (construction of initial model and definition of objective function).
