摘要
本文在非均匀流场中规则波折－绕射缓坡方程的基础上，引入谱的概念，建立了用方向谱表示的非均匀流场中随机波折－绕射缓坡方程，并选用文圣常等提出的解析方向谱作为靶谱，就一模型海区进行具体的数值计算，结果表明，随机波折－绕射模型要明显优于规则波的折－绕射模型。
Based on the mild - slope equation of regular waves, a numerical model in terms of directional spectrum is presented for the prediction of combined refraction - diffraction of random waves propagating in the region of non - uniform currents. By choosing the directional spectrum given by Wen et al. the numerical computation is carried out in an experimental sea region and the result shows that the model of combined refraction - diffraction of random waves is obviously superior to that of the regular waves.
