实测海浪谱中理想的单峰谱是不多的,多数有几个尖峰。如果谱的主能量峰占相当大的优势,可称之为准单峰海浪谱。在南海东北部海区的50个实测海浪谱中,准单峰海浪谱约占60％。准单峰海浪谱中,有少数可以用规则海浪谱较好地以合,如图2所示。规则海浪谱是单一均匀、稳定风场作用下,不考虑海底摩擦和海流作用的理想海浪谱模式,作者在文献[3]中进行了讨论。准单峰海浪谱中,绝大多数属于混合型单峰海浪谱,
The ideal single peak spectrum in the sea spectrum is small, most of them have several spikes. If the spectrum of the main energy peak account for a considerable advantage, it can be called quasi monomorphic wave spectrum. Among the 50 measured wave spectra in the northeastern South China Sea, the quasi-single-peak wave spectrum accounts for about 60%. Quasi single-peak wave spectrum, there are a few can be better with the regular wave spectrum in order to, as shown in Figure 2. The regular ocean wave spectrum is a single uniform and stable wind field and does not consider the ideal ocean wave spectrum of ocean floor friction and ocean currents. The authors discussed in [3]. Quasi single peak wave spectrum, the vast majority belong to the mixed single peak wave spectrum,
