| 摘 要： | 从理论与模型算例两方面对一种以Ｐａｒｋｅｒ公式为基础的频率域位场反演方法做了进一步深入研究。表明它是一种能够更有效地引入低通滤波因子的迭代方法。与改进的正则化稳定因子相结合，提出新的快速正则化反演方法。除了将其用于反演求解均质界面以外，它也被推广至变物性的界面反演以及物性反演

| Abstract: | A potential inverse method in the frequency domain has been presented, based on Parker formula. It is studied thoroughly in both the aspects of theory and model experiment. It is shown that a low pass filter can be used the most effectively in this iterative method. Combined with a stable regularizing filter, a new fast regularizing inversion is put forward further. Besides a single homogenous boundary, this inversion has been extended to solve the problems of a non homogenous boundary and density or magnetization distributions. The applications of the above methods in some petroleum prospecting areas show that they are extremely effective. |
