| 摘 要： | 在三阶海浪非线性波高分布模式的基础上，引进描述分布函数结构形式的重要统计量，即概率分布的离差系数与偏差系数。给出这两个统计量与非线性控制参数之间的解析关系式，从而给出了反映风浪不同状态下的波高分布特征。与传统的瑞利分布相比，本文的结果有更广泛的实用意义。并把理论结果应用于黄河口波浪统计学的研究。

| Abstract: | Based on the model of distribution of the third order nonlinear wave height, twosignificant statistical parameters, dispersion coefficient Cv and deviation coefficientCs are used to describe the structure of distribution function. This paper discussesthe important case in which the change of Cv or Cs obviously affect the distributionof probability density. The analytical relation between the two statistical parametersand the nonlinear governing parameters is obtained in order to reflect the charactersof distribution of wave height in different wave state.Compared with the Raleigh distribution in which Cv and Cs are constant, thepresent results have important application in tlie real sea because Cv and Cs are functions of nonlinear governing parameters and change with different wave state.Use of the results to study the statistics of Huanghe River estuary showed thatthe theoretical curves coincide with the data points. |
