In the end, as an application of the formula derived in this paper, we estimate the innermost zone effects of the gravity recovery from ERS-1 altimetry data for an area of 6 °× 6 ° in North Atlantic, and analyze the results of the estimation. 最后利用ERS1卫星测高数据,根据本文提出的方法计算垂线偏差分量,采用本文导出的内区效应公式计算了北大西洋6°×6°区域内区效应对测高重力结果的影响。
