| 摘 要： | 本文利用现场观测数据、实验室风浪槽观测数据和由文氏谱及JONSWAP谱生成的模拟数据,研究了有效周期与谱平均周期、谱峰周期与谱平均周期以及有效周期与谱峰周期的关系,通过数据拟合给出了相应的关系式.研究发现,有效周期与由谱的负阶矩计算的平均周期之间的关系更加稳定,并且有效周期与负2阶矩计算的平均周期几乎相等,均代表了海浪主导波对海浪平均周期的贡献.

| Abstract: | In the present paper, the field data, the laboratory data from wind wave flume and the simulated data generated by Wen's and JONSWAP spectra have been applied to investigate the relationships between the significant wave period and the spectral averaged period, between the wave period at spectral peak and the spectral averaged period, and between the significant wave period and the wave period at spectral peak. The corresponding formulae are presented by data fitting. It is found that the relationship between the significant wave period and the spectral averaged period calculated with the negative order spectral moment is more stable, and that the significant wave period is almost identical to the spectral averaged period calculated with the minus 2 order spectral moment, both of which demonstrates the contribution of the dominant wave to the averaged wave period. |
