本文首先提出一种基于量纲分析的风浪谱平衡范围斜率的线性模式。依此模式,谱斜率从深水的-5连续变化到浅水的-3。但是,这种模式给出的结果与实测数据有较大的差异,于是,又提出了一种非线性模式。尽管这种非线性模式的推导借助了某些假定和经验事实,但给出的结果良好地符合实测数据,并能解释一些线性模式所不能解释的现象。 In this paper, we first propose a linear model based on the dimensional analysis of the slope of the wind-wave spectrum balance range. In this mode, the spectral slope changes continuously from -5 for deep water to -3 for shallow water. However, the results given by this model are quite different from the measured data, so a non-linear model is proposed. Although this derivation of non-linear models draws on some assumptions and empirical facts, the results presented are in good agreement with the measured data and explain some of the phenomena that linear models can not explain.
