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。
Based on the non-linear wave height distribution model of the third-order wave, an important statistic describing the structural form of the distribution function is introduced, that is, the dispersion coefficient and the deviation coefficient of the probability distribution. The analytic relation between these two statistics and the nonlinear control parameters is given, which gives the wave height distribution under different states of wind and waves. Compared with the traditional Rayleigh distribution, the results of this paper have more practical significance. The theoretical results are applied to the study of wave statistics in the Yellow River Estuary.
