摘要
研究了日月潮汐改正对精密水准测量的影响,推导出了一种水准测量中可以采用的简单快捷的日月潮汐改正实用模型,并与其他相应模型进行了比较和分析,表明了该模型的实用性和可行性,可应用于海洋测绘中海面地形的确定。
The effect of lunisolar tides on the precise levelling is investigated in the paper.A quick and practical model of the correction of lunisolar tides that can be used in the levelling is presented.Compared with other similar models,the result confirms the practicability and feasibility of the model that can be applied to determine sea surface topography in ocean mapping.
