| 摘 要： | 本文论述了海潮对重力固体潮观测的影响,把整个褶积计算分为近洋区及远洋区两部分,其中近洋区采用格林函数进行数值积分的方法,远洋区则利用全球海潮潮高的球函数展开式。着重讨论了远洋区的实施方案,导出了必要的工作公式,并就加速远洋区级数收敛问题作了探讨。利用导得的公式,计算了M2海洋潮波对中国境内重力观测的影响。

| Abstract: | In this paper, we deal with the effect of oceanic tides on the gravity observations. Calculated convolution integral is divided into two parts: the near ocean area and the far ocean area. The method to integrate numerically Green's function is adopted in the first part. The second part, however, uses a spherical harmonic expansion of oceanic tides on the whole globel. We pay treat attention to the working plan for the far.ocean area. Calculated formulas and coefficients concerned are given, and the problem to speed up the convergence of series is studied. By using the formulas obtained, we have calculated the effect of M2 constituent on the gravity observations in the region of China. |
