摘要
本文叙述了非迭代、非线性二维重力反演方法的原理、模型计算及应用效果等。与以往诸多的求界面重力反演方法相比，该法的主要特点是：将界面的深度用一幂级数的形式表示，且幂级数系数的计算与界面上下地层的密度差无关。因此，一旦求出了幂级数的系数，由界面的密度差可直接得到界面的深度，且幂级数收敛的速度很快。
The principle, programing, model calculation of the two dimensional noniterative nonlinear gravity inversion are described. Comparing with the previous methods, this method is mainly characterized by that the depth to the interface is expressed by a power series, that once the series coefficients have been computed, the depth to the interface can be calculated immediately using the density contrasts, and that the convergence of the power series is very fast. The effect of the method is well showed by the model calculation and field example.
