| 摘 要： | 利用最小二乘法对潮汐实测资料进行分析,如何选择分潮是提高分析预报精度的关键。本文利用在频率域对潮汐振动特性进行分析的方法,可以客观地了解潮汐过程中存在着哪些振动,由此只要用较少的分潮就能组成精度较高的分潮模式。并以对连云港潮汐的分析预报,作了实例验证。结果表明,本文的方法可以避免选择分潮时的盲目性和偶然性,从而使潮汐分析预报的精度得到提高。

| Abstract: | With the method of analysing tidal oscillation characteristic in the spectral field, what kinds of oscillations existing in tidal process can be known objectively so that the constituent model composed of only fewer constituents will be higher accurate. The method is used to analyze and predict the tide data in the Lian Yung Gang. Results show that selecting constituents blindly and contingently may be avoided with the method and the accuracy in analysis and prediction will be improved. |
