| 摘 要： | 本文给出与时间无关的海潮负载对台站位移影响的公式,利用经我们改进的程序,计算了8个主要分潮波对国内台站的海潮负载效应在地面和地心直角坐标系各分量所引起位移的振幅和位相。计算结果表明,对我国台站影响最大的分潮波是 M_2、K_1和 O_1,1990年期间由海潮负载引起台站的总位移值的极大值具有明显的22.5小时和13.6天左右的变化周期。

| Abstract: | The time-independent ocean tide loading correction formula for station displacement is derived.From a developed program,the ocean tide loading effects of 8 ma- jor tidal components on Chinese stations in both topocentric and geocentric rectangular croodinate systems are calculated.It is showed that the maximum influence of ocean tide loading on Chinese stations is from M_2,K_1 and O_1,and the maximum values of total station displacements due to ocean tide loading appear to have variation periods of about 22.5 hours and 13.6 days during the year 1990. |
