潮汐模型 meaning in Chinese
tidal model
Examples
- Physical tidal model
实体潮汐模型 - Following the launch of topex / poseidon in 1992 , there has been considerable improvement in the accuracy of the global tidal models
Topex / poseidon的发射极大地促进了大洋潮汐模型研究的进展，但大洋模型在浅海区域精度比较差。 - Based on systematical study of each constituent of iss , the foundation , computation and precision analysis of the models of geoid , sea surface topography , mean sea surface and ocean tide are mainly discussed ; the conceive of mean sea surface height model and ocean tidal model suitable to chinese near sea and its neighborhood is provided ; two kinds of iss model are derived out
本文在系统研究瞬时海面高各组成要素的基础上，主要讨论了大地水准面模型、海面地形模型、平均海平面模型和海洋潮汐模型的建立、计算以及精度评价等问题；提出了建立适于我国近海及邻域平均海平面模型和海洋潮汐模型的设想；综合得出了两种瞬时海面高模型，并进行了精度估计，编制了相应的软件。 - However , the application of global tidal model to the study of shallow sea tides is much worse in the accuracy . tidal signal in topex / poseidon altimetric data is the largest contributor to sea surface height variability and accounts for more than 80 % of the signal variance . so it is urgent to develop tide model in the shallow area wi th high accuracy
潮汐是高度计资料海面变化中最大的成份，占总变化80以上，伴随着卫星高度计资料在海洋研究中的广泛应用，发展基于卫星高度计资料的高精度浅海潮汐模型成为进一步利用高度计资料研究其它物理海洋问题的基础。
