本文将位场重力数据变换成下半空间物理性(密度)的分布,该法采用设定的物理特性差和数据误差上限进行约束。它有两个处理步骤。首先,把数据转换成与线(2D情形)或点(3D情形)等价的数据集,用Euler均匀方程迭代估算最大剩余数据值。然后,把这些值变换成体积-密度积,并通过“气泡法”给出的密 In this paper, the gravity field data of the field is transformed into the distribution of the physical (density) in the lower half. The method uses the set physical properties and the data error upper bound. It has two processing steps. First, the data is transformed into a data set equivalent to a line (2D case) or a point (3D case), and the maximum residual data value is iteratively estimated using the Euler uniform equation. Then, transform these values ​​into volume-density products, and pass the density given by the Bubble Method
