摘　　要：利用重力等值原理,求物体质心的方法,针对高精度重力测量中常见的地表地形、地物的重力异常影响,提出了一种近区地表地物的改正方法。Considering A method of gravity correction for ground objects and topography has been developed by using the equivalent principle of gravity to derive centroids. Utilizing the principle of asking centroid and aiming at the common topographical surface feature in high-accuracy gravity measurement, a topographic correction method near gravity survey districts is provided in this paper.

关 键 词：近区重力改正 地表地物 质心
