摘　　要：用重力异常数据反演多层介质密度分界面的数值反演方法，把的正则化方法推广到解第一类积分方程组，利用解的先验信息和物探资料，建立了一个优选正则化参数组的原则，从而得到了最优正则解．该方法已在计算机上实现．不仅理论模型反演结果正确，而且已有效地应用于实际重力资料的反演和解释．This paper proposes an inversed method to inverse the multi-interfaces of density which is applied to the gravity anomaly,and develops certain theoretical basis.Using prior information and geophysical practice to institute the rule of choosing the system of regular parameter, we have generalized. A. H. TNXOHOB's regularized method to solve the system of integral equation of first kind,and have gained the optimal regular solutions.This method has been realized in computer.It is not only corrected for the inversed solutions of theoretical models,but also used in practical gravity data inversions and explanations effectively.
