By analyzing the spectrum of the random oceanwave and of the force of the ship, the ocean wave model and the ship movement model are erected.
在分析随机海浪的波能谱和船舶的受力情况的基础上，建立随机海浪模型和船舶运动模型。
2
The geometry structure of sea surface was formed with the wavespectrum model of oceanwave in the paper.
主要工作是对利用海浪谱模型，生成了海洋表面几何构形。

The power spectral density of ship's motion is calculated based on oceanwave energy spectrum and the movement spectrums of the ship's random motion are calculated and created.
