一、引言 在研究波浪预报模式和设计海洋构筑物时,都需要波谱的表达式。自劳曼1953年第一次介绍了他的风生波谱表达式以帮助波浪预报的三十年来,海洋学者试图研究一种精确的和实用的波谱表达式。到目前为止,国内外发表的波谱形式不下数十种。如Pier-son—Moscowitz谱、Bretschneider谱、Brets-chneider—Mitsuyasu谱、Jonswap谱、 I. INTRODUCTION In the study of wave forecasting models and the design of marine structures, spectrum expressions are required. For the first time in 1953, Lauman introduced his wind-spectroscopy expression to help predict waves. Oceanographers attempted to study a precise and practical spectrogram. So far, no fewer than a dozen spectrum formats have been published at home and abroad. Such as Pier-son-Moscowitz spectrum, Bretschneider spectrum, Bretschneider-Mitsuyasu spectrum, Jonswap spectrum,
