The diurnal springs correspond to the semidiurnal neaps and vice versa . 全日潮大潮对应于半日潮小潮，反之亦然。

The assimilation scheme uses a blending approach based on optimal linear interpolation . the improvement is 45 % for the phase - lag of s2 after assimilating the altimetric data of the crossover points , while the correction for the diurnal constituents is not so good as for semidiurnal constituents 利用基于最优插值法的混合法将交叉点的调和常数同化到动力模式中，同化后s _ 2分潮的迟角精度改进最大，可以改进45 ，结果显示高度计资料的分析结果对模式结果的精度影响很大。
