| 摘 要： | 通过比较光易型和我国规范中两种不同的方向分布函数,表明我国规范推荐的方向分布函数表现为风浪和传播距离较短的涌浪特征,并与光易型方向分布函数有很强的一致性。认为方向分布函数应与频谱联合分析,才能更好地反映天然的海浪。通过分析我国近海几个区域的方向谱特征,均反映理论分布的特点,方向集中度略小于规范推荐的情况。

| Abstract: | By comparing two different directional distributions,it's shown that the directional distribution recommeded in the nowaday specifications in China is characteristic of wind wave and swell with short propagation distance and in good agreement with Mitsuyasu direction distribution.It's considered that natural sea wave will be reflected well,when directional distribution is analyzed combining frequency spectrum.From analyzing the characters of directional spectrum in several offshore areas in China,it's known that directional concentration is slightly less than that recommeded in the spe-cifications. |
