摘要
推导了双磁性界面模式正反演公式，并提出解决反演发散问题的新算法，讨论算法实现的关键技术和措施，通过模型试验分析算法的精度和可用性。结果表明：新算法能够保证反演过程稳定收敛；计算精度高，误差绝对值为0．01％-4％，且具有一定抗噪能力。用新算法处理中国某地磁测数据，得到的反演结果较为合理。
Forward and inversion formulae of two-interface pattern was deduced, and an approach to solve inverse divergence was proposed. The key issues and techniques about implementation of Parker method were analyzed. The precision and usability of the method were proved through the model examination. The results show that the method can premise inversion converge stably. The method has high calculation precision and the absolution of error ranges from 0. 01% to 4%. The method also has antinoise property. Furthermore, the method was used to process field magnetic data of somewhere in China and the inversion results are reasonable.
