目前,在海洋、海岸工程中,对海浪波高与周期的一元概率分布,单独有较深入的研究。但对它们的二元分布(即联合分布),不管是理论上还是实践上,都探讨得很不够。六十年代,苏联的基于波高和周期相互独立的假设,给出了波高和周期的联合分布。七十年代,英国海洋学家Longuet-Higgins基于波浪是窄谱的假设,导出了波振幅和周期的联合分布。但由于这些假设都与实际的海浪现象,有较大的差异,因此,在实际应用上受到了很大限制。近年来,我国海洋工作者应用概率定理建立了浅水周期与波高的联合分布,开辟了一条新途径。
At present, in ocean and coastal engineering, the univariate probability distribution of the wave height and period of waves is separately and deeply studied. However, their bivariate distribution (ie joint distribution), both in theory and in practice, are not enough to explore. In the 1960s, the Soviet Union gave a joint distribution of wave height and period based on the assumption that wave height and period are independent of each other. In the seventies, the British oceanographer Longuet-Higgins derived the joint distribution of wave amplitude and period based on the assumption that the wave is a narrow spectrum. However, since these assumptions are different from the actual phenomenon of ocean waves, they have been greatly restricted in practical application. In recent years, the marine workers in our country have established a joint distribution of shallow water cycle and wave height using probability theory and opened up a new way.
