本文提出了一种简易快速的重力基点网平差方法.平差后的基点重力值可通过建立和求解结点平差值方程组直接获得,并能在求解方程组的中间计算过程中一次获得全部基点上的权倒数值.此方法与目前在重力基点网中常用的条件平差方法相比,其原理和数学过程较简明易懂,计算也快速方便,并且能适用各种网形结构较复杂的基点网的平差计算.

In this paper, a simple and rapid technique for gravity base-point net adjustment was presented. The gravity value at each base-ponint after adjustment could be obtained by establishing and solving the system of equations of nodal adjustment values. The values of weight reciprocal at all base-points could also be obtained at a stroke in the process of calculation. Compared with the conditional adjustment commonly used at present, the technique recommended has the following merits: it is simple and easy to understand, both for its principle and math procedure} it has the advantage of easy-running and convenient for calculation; it is suitable for the adjustment of all sorts of base-point nets with complex structure.
