利用我国南极中山站2000-02~2005-10的验潮数据,采用调和分析得到了中山站附近海域潮汐170个分潮的调和常数。对调和分析的结果进行统计分析,发现了传统调和分析方法的局限性,提出了提高调和分析分辨率的方法——采用更高的采样率或使用更长时间的数据,给出了中山站的主要潮汐特征值及工程潮位。
The harmonic constants of 170 tidal constituents at Zhongshan Station, East Ant- arctic are obtained from the tide data lasting from Feb. 2000 to Oct. 2005 using classic har- monic analysis method. Chi-square test is applied to the residual, which demonstrates the disadvantage of the classic harmonic analysis. A higher interval of the tide data or a longer period of data is suggested to be adopted to improve the distinguishability of tidal constitu- ents. Results of the harmonic analysis show that the tide type of Zhongshan Station isirregu- lar diurnal tide. The main tidal characteristic value and engineering water level are also calcu- lated.
