In the light of characteristics of analytic continuation and odd points of the potential field function, the authors, using the principle of normalization, deduced the normalized total grads method, and conducted a basic theoretical study on the application of this method to "mise-a-la-masse" technique. In addition, the normalized total grads method was used to interprete the model experimental result of direct charge, the theoretical computational result of indirect charge of near-ore wallrock, and the field observational result. It is proved that the normalized total grads vertical sections and the plans at different depths can be employed to determine central depths of anomalous bodies quite satisfactorily and to define roughly some other geometric parameters. Hence, the fairly good initial profile can be provided for further inversion of electrical parameters.
