Abstract: Basing on the co-variance functional method, the wave spectra of Huanghai (Yellow Sea)area are estimated in this paper. The digital filter techniques and probabilistic properties about x, D, σ, Cv, Cs, Ce are analyzed and discussed. The computation of wave spectra is made on the computer by using co-variance functional method and fast Fourier transformation (FFT)method, the efficiency of the computation by FFT method is increased.

摘要： 在海港工程,海上采油工程的设计建造中,波浪要素设计值是最基本最重要的水文要素之一,目前设计波浪的推算主要采用两种方法,一为特征波法,一为波谱法。在一些国家的现行规范中后者业已被采用。我国海港工程、海上采油平台规范中主要应用特征波法,但对波谱法也有所反映。
