近年来，由于需要建立更真实的地球物理结构（如沉积盆地）模型，变密度对比在重力反演中的应用越来越重要。线性，二次和指数变化，无论是在空间或在频域中，是几种方法的基础。除其他外，见Granser（1987）、Chai和Hinze（1988）、Reamer和Ferguson（1989）以及Rao等人（1990）的论文。Guspi（1990）使用多项式密度-深度函数将重力异常反演为空间域中的二维多边形。
The use of variable-density contrasts in gravity inversion has gained increasing importance in recent years due to the necessity of constructing more realistic models of geophysical structures such as sedimentary basins. Linear, quadratic, and exponential variations, either in the space or in the frequency domain, are the basis of several methods. See, among others, the papers by Granser (1987), Chai and Hinze (1988), Reamer and Ferguson (1989), and Rao et al. (1990). Guspi (1990) used polynomial density-depth functions for inverting gravity anomalies into 2-D polygons in the space domain.
