陆地区域重力测量在全球开展已有几十年的历史，然而，迄令为止，重力异常的各项外部改正仍然存在许多问题，如自由空间改正系数的取值、中间层物质密度的选取以及地形影响值的计算方法等，本文试图就这些问题结合我国区域重力测量的情况谈一些看法，以供从事这方面工作的同志们参考。 However, as of now, many external corrections of gravity anomalies still exist many problems, such as the value of free space correction coefficient, the selection of the density of the middle layer material and the topography The calculation method of influence value, etc. This article attempts to talk about some of these issues in combination with the situation of regional gravity measurement in our country for the reference of comrades engaged in this field.
