摘　　要：论文基于长期验潮站数据分析结果,利用实际分潮的振幅比和迟角差,在传统的分潮合并理论的基础上,设计和实现了一种新的用于月尺度和年尺度分析的交近点改正方法,目的在于精化潮汐参数的提取,提高短期潮汐分析和预报的精确度。论文给出了合并模型的具体推导过程和计算方法;做了厦门某验潮站548分潮19年的潮汐调和分析,得出相应分潮的调和常数,将选取分潮的振幅比和迟角差用于潮汐短期调和分析;实验验证表明利用新的分潮合并策略进行的潮汐月调和分析和年调和分析得到的调和常数更加接近分潮的长期分析结果,有效提高了潮汐参数的分析精度。In this paper,a new model of node and perigee correction by using amplitude ratio and phase lag differences of ac-tual constituents from the analyzed results of long term tidal stations is developed for tidal parameter refining and precision of tidal analysis and prediction improving.In this paper,the derivation process and calculation method of the constituents combined model is shown,the short term tidal analysis is done in the use of amplitude ratio and phase lag differences of chosen constituents which come from the 19 years tidal analysis of 548 constituents in one Xiamen tidal station.The experiment for tidal analysis of monthly and yearly water level observation series indicates that the results are closer to ones from long term tidal analysis,the accuracy of harmonic constants are improved effectively.
