重,磁界面计算的广义反演方法

介绍一种重、磁界面计算的广义反演方法。该方法的主要特点是引入了模型参数的协方差矩阵使得反演过程能够利用模型参数的先验信息而加快收敛速度。文中首先给出了失代公式，并给出了详细算法。其次，通过理论模型的计算对方法作了测试。根据这些测试结果，重点讨论了Ｃｍ在反演中的作用。最后给出了一个应用实例，并与频率域方法作了比较。

GENERALIZED INVERSION METHOD ON THE COMPUTATION OF GRAVITY AND MAGNETIC INTERFACES

In this paper,the generalized inversion method on the computation of gravity and magnetic interfaces is presented.The main characteristic of the method is that it introduces a prior information matrix (Cm) of model parameters,and fastens the convergence of the iteration process.The iteration formula and detailed algorithm are given and the method is examined through the computation to theoretical models.The function of Cm in computation of interfaces are discussed in detail according to the examined results.Finally,a applied example is illustrated and the result of generalized inversion method is compared with the result of frequency domain method.
