中文摘要：
为得到更接近地下真实分布的反演界面,笔者比较分析Parker-Oldenburg反演和改进迭代反演,发现改进迭代反演方法不仅可以避免计算放大项,而且能够得到更好结果。通过理论模型,对经典Parker-Oldenburg方法和改进迭代反演方法的计算速度、迭代收敛性和结果精确性进行比较,结果表明改进迭代反演方法在保证计算速度和迭代收敛的情况下,能获得更精确的地下界面结构。通过实际数据验证了改进迭代反演的有效性和实用性。
英文摘要：
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 amplifying 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.
