Abstract:We present some simple practical 1一D inversion methods,including Ecstick inversion method and the method which approximates magnetotelluric field by direct current field, The principles and formulas are described,and the computations on regular models are made to check their inversion effects.It is shown that Eostick inversion method locates the bottom interface more correctly than other interfaces,The effect of direct current approximation depends on approximating schemes,Among the five schemes as mentioned in this paper,the best is the scheme which assumes that direct current field dee.ys with total longitudinal conductance in the form of exponential function.
