摘要
用变维分形方法（分维数是特征线度的函数,而不是常量）分析了与实测谱值符合良好的Hong—Yang谱,根据分析结果讨论了用分形方法对实测谱值的拟合与插值,效果很好。文中还证明,各种形式的风浪频谱均可转化为变维分形的形式。
Hong-Yang spectrum which coincides better with the measured spectral values are analyzed with the variable dimension fractals (the fractal dimension D is the function of characteristic scale r instead of a constant). On the basis of the analyzed results,the fitting and interpolation of the measured spectral values by using the variable dimension fractals are discussed, and good results are achieved. This paper proves that all the forms of wind wave frequency spectrum can be converted into the forms of variable dimension fractals.
