Abstract：Pseudo-linear approximate method is approximate method presented by Mr.Zhdanov during the process of study on forward and inversion problems of electromagnetic scattering.Because the similarity between integration equation of stable current field and integration equation of electromagnetic scattering,the pseudo-linear approximate method can be used to study the issue of stable current field.The key that determines the method being effectiveness is whether the simple and feasible method can be used to calculate the parameter λ.The paper mainly discussed the variation rule of parameter λ in some common simple geoelectric models.The studied results showed that the parameter λ can be considered as slowly changed function of position in common scenario of direct current (DC) electrical prospecting and can be acquired by simpler method.This study laid a foundation for using pseudo-linear approximate method to realize the rapid inversion of stable current field.
