摘　　要：对我国近海厦门、大连、北海、连云港、坎门、汕尾、东方、海口、香港北角、名濑、那霸、吕四、闸坡、石臼所共14个验潮站多年潮汐资料进行了分析。对1 a调和分析结果中的8个分潮(Q1,O1,P1,K1,N2,M2,S2,K2)进一步进行了分离,得到各分潮的调和常数,并和1 a潮汐调和分析中的假定值进行了比较。结果表明,有些分潮存在较大误差。用19 a分析所得的调和常数代替传统1 a分析的假定值,能够提高潮汐分析和预报精度,减小误差。Harmonic analysis of long-term sea level observations at the 14 tidal stations i. e. Xiamen, Dalian, Beihai, Lianyungang, Kanmen, Shanwei, Dongfang, Haikou, Beijiao of Hong Kong, Naze, Naha, Lusi, Zhapo and Shijiusuo, is conducted. The result consisting of 8 constituents（Q1 ,O1 ,P1 ,K1, N2 ,M2, S2 and K2） obtained from the one-year data analysis are seperated to respectively derive harmonic constants of each constituents and to compare the derivedharmonic constants with those assumed values in the traditional one-year data analysis. It is shown in the comparison results that there are significantly errors of some constituents. If the harmonic constants resulting from the 19 year data analysis are used to substitute for the assumed values in the traditional 1 year data analysis, the accuracy in the tidal analysis and forecast can be raised and the errors can be reduced.
