研究了潮流(准)调和分析方法中的一些细节问题,包括:建模所需分潮数量的选取、交点因子和交点订正角的时变性以及中短期数据分析时引入的差比关系的准确性,并得出:忽略一些次要分潮的调和分析虽然在模型拟合精度上有所降低,但其对主要分潮的分析结果影响较小;除多年数据分析外,交点因子和交点订正角的时变性对调和分析结果影响一般较小;潮流中短期数据分析中引入的差比关系须由较为准确的潮流参数提供,而不能由潮汐参数提供。
Some details of the tidal current (quasi) harmonic analysis method are studied, including the selection of the amount of moisture needed for modeling, the time-varying of the intersection point and the correction angle of the intersection point, and the accuracy of the difference ratio introduced in the short-term data analysis The results show that although the harmonic analysis ignoring some sub-tidal components has less effect on the model fitting accuracy, it has less effect on the analysis results of the main tidal components. In addition to years of data analysis, the intersection point and the correction angle The time-varying effects on the harmonic analysis results are generally small; the difference ratio introduced in the short-term data analysis of the tidal current should be provided by the more accurate tidal current parameters and not by the tidal parameters.
