| 摘 要： | 若把河口潮位时间序列简单地看为单输入和输出线性系统模型的输入输出信号，借助频谱分析可以将它们在频域内的关系建立起来，用来进行潮位序列的插补，带通滤波技术的应用可使模型的计算精度大大提高

| Abstract: | The tidal level series in estuary area,as a kind of time series,may often be regarded as a set of input or output signals of the liner system model.In this paper,the numerical relationship of the signals,in frequency region,has been established by computing cross spectra,to which band pass filtering has been applied,for the purpose of raising precision of the numerical simulation. |
