摘　　要：对一年潮流实测数据进行了调和分析试验研究。通过对实测数据和模型残差的频谱分析,验证了调和分析模型及其结果的正确性,并在理论上对模型残差的组成进行了分析,由结果可知,短期气象因素和季节性变化异常是造成调和分析模型偏差的主要因素,且该偏差可能具有较大量级。The harmonic analysis of one year flow data file was carried out in this paper.Based on the spectrum analysis of measured data and residual error of the model ,the validity of the harmonic analysis model and its results were verified.The composition of residuals was also analyzed theoretically.The results show that short-term variation anomaly of meteorological factors and seasonal variation are the main factors to cause the deviation of harmonic analysis model which may present larger deviation.
