To get more accurate interface of inversion��the authors compared Parker- - Oldenburg inversion with improved iteration inversion��and found out that the improved iteration inversion not only avoids calculating the am- plifying term��but also gets better results�� Applying Parker-Oldenburg inversion and improved iteration inversion in theoretical model��through the speed of calculation��convergence of iteration and accurateness of results based on density interface��we drew the conclusion that the improved iteration inversion can obtain a better structure relief of the underground in the case of ensuring the calculation speed and convergence�� The effectiveness and utility of the improved iteration method can be verified by real data��
