| 摘 要： | 将研究区域划分成具有固定宽度的矩形网格，以网格密度和厚度作为模型参数，在此基础上形成重力异常的反演目标函数，计算出对模型参数的偏导数矩阵，然后采用脊回归法对重力异常进行反演而同时得到密度及其界面。以此方法对理论模型进行了反演试验。

| Abstract: | The research region is divided into many rectangles with fixed width, and densities and thicknesses of the rectangle units are taken as model parameters. On this base, the objective function of inversion of gravity (anomaly) is formed, and the partial derivative tensors for the model parameters are also calculated. Then the Ridge Regress Procedure is employed to inverse gravity anomaly in order to obtain the densities and their interfaces.The method is used in inversion test for two theoretical models. |
