潮汐调和分析的一种算法

A TIDAL HARMONIOUS ANALYSIS METHOD

本文在常规潮汐调和分析方法的基础上，提出了一种由高低潮资料进行潮汐分析的算法。具体计算表明，该算法与现今通用的常规算法（即等间隔最小二乘法）相比，既可大大减少所需原始样本量，在相同记录长度内，是常规算法的三分之一还少，同时减少样本处理的前期工作量；又能保证潮位拟合的精度和预报的可信度，两者精度相当，结果一致。该算法原理简单、实用有效，对于局部样本缺损较易处理，具有实际应用价值。

Based on the conventional tidal harmonious analysis method (that is, an equal interval least square method), this paper has developed a new method for the calculation of tidal harmonious constant using high and low tide data. Some examples show that this method needs only less than one third observational samples compared with the conventional method, and that the work load for processing date is largely reduced. On the other hand, this method is consistent with the conventional method in precision of fitting tidal curve and reliabity of tidal prediction. This method has the advantage in calculation principle, application validity and treatment, easy in case of the lack of data, so it has a practical value.
