中文摘要：

海浪通常以风浪和涌浪混合的形式存在。文中利用模型试验和实测资料,对目前提出的一种二维谱风涌浪分离方法（2D法）和3种一维谱风涌浪分离方法（PM法、WH法、JP法）进行了检验,分析发现：2D法给出的结果整体而言最为可靠,与2D法相比,PM法明显高估了风浪成分,WH法低风速时高估了风浪,高风速时跟2D法比较接近,而JP法在整体上高估了风浪成分。通过调整分割频率的比例系数,改进了PM法,改进后的PM法给出的分离结果与2D法最为一致。

英文摘要：

The ocean waves are generally a mixer of wind-wave and swell.In this paper,a two-dimensional（2D） wave spectrum partitioning techniques and three one-dimensional（1D） wave spectrum partitioning techniques（i.e.PM technique,WH technique,JP technique） used to identify wind-wave and swell are examined based on the model results and the observations,it is shown that the 2D technique could provide most reliable results;compared with 2D technique,PM technique obviously overestimates the wind-wave components,WH technique overestimates the energy of wind-wave at low wind speed,while shows better agreement with 2D technique at higher winds,overestimations also occur in the case of JP technique;PM technique is modified to show better agreement with the 2D scheme,it is found that the improved PM technique provides most consistent results with the 2D scheme among the 1D techniques.
