| 摘 要： | 地球物理反问题存在多解性和不稳定性,正则化是得到稳定解的重要手段。正则化方法中稳定因子的设计与正则化因子的选择是两项重要研究内容。以大地电磁测深法为例,研究了正则化因子的"L"曲线法自动选择算法;针对不同的稳定因子,研究了稳定因子的特点及稳定因子内部参数的选择原则。研究工作为大地电磁反演提供支持。

| Abstract: | Multiple solutions and instability are existed in geophysical problems, regularization is an important method to obtain a stabilizing solution. The design for stabilizing factor and the choice of regularization factor are two important research contents in the regularization method. In this paper, it is taken magnetotelluric method for instance, studying the auto-selecting method of the regularization parameter through L-curve criterion. It is studied that the characteristics and the selecting principle of the stabilizing factor for different stabilizing factors. The studying work provide the support for the inversion of the magnetotelluric. |
