事实上，真正的海况应该用三维波浪来描述。到目前为止，二维波浪通常用于预测真实海洋的运动。这并不准确。本文从频域、时域和模型试验两方面研究了波浪传播对船舶运动的影响。三种方法的结果一致性较好。结果表明，在实际海洋运动预报中，考虑三维波浪的方向性影响是非常重要的。
In fact,real sea states should be descripted by three-dimensional waves.By now,tow-dimen-sional waves are usually uesd in predictions of motions in real seas.It is not accurate.In this paper,influnces of wave spreading on the motions of ship were studied in frequency domain,time domain and by model test.The agreement found in the resullts of three methods is good.The resluts show that the effects of wave direc-tionality of 3D waves are very important to take into account in prediction of motions in real seas.
