【摘要】 利用风浪实验资料，系统地研究了列率谱随风速、风区的演变规律。与频率谱的计算结果比较表明；在主含能频段，特别在峰频附近，两种谱估计方法所得结果基本吻合。但在高频段，特别在二倍峰频附近，两种谱估计方法所得结果存在明显差异。文中就其存在的差异给出了可能的物理解释。更多还原

【Abstract】 The evolution of scquency spectrum is systematically investigated by the use of the wave records under different wind speeds and fetches. A comparison of the measured results obtained by means of frequency spectral method and sequency spectral method indicted that in the main part of the spectrum, especially near the peak frequency of the spectrum, they could basically fit each other. At thigh frequencies, however, especially at the frequencies near the twice the peak frequency, the difference between the two spectral methods are most significant. The reasons why the difference exist are also discussed so as to propose a probable physical explanation.更多还原
