As the sun sank in the late afternoon , a brisk wind from the ocean whipped up whitecaps 夕阳西下，一股凉爽的风从海上吹起白浪。

Don ： heading into the night , head on into the waves ! the stars my only guide as we break through the whitecaps . through storms , wind , and rain we sail 唐：在黑暗中前行，迈向海浪！当我们乘风破浪时星辰是仅有的向导。我们航行，穿过风雨浪涛。

The seas were all of an eighth of a mile apart , and the wind snatched the whitecaps from their summits , filling the air so thick with driving spray that it was impossible to see more than two waves at a time 海水间隔有一英里的八分之一宽，强风捉住浪潮的顶端，厚厚一大片地席卷到空中，所以我无法同时看到两层海浪。

Part i : since the study about breaking onset criteria base on the downward acceleration or on the wave slope shows great discrepancy , the models that estimating breaking probability and whitecap coverage according to these two . criteria are problematic 第一部分：因所采用的动力学或波陡判据的不确定性和海浪谱四阶矩的难以确定，现已提出的关于风浪破碎率和白浪覆盖率的统计模式有一定的不确定性。

The first part is a statistical study about the probability of wave breaking and the fraction of sea surface covered by breaking water ( ie . whitecap coverage ) , while the second part is a dynamical study about the influence of nonuniform current fields on the breaking of short wind waves 本文内容包括两个部分，第一部分是风浪破碎率和白浪覆盖率等破碎统计特征量的统计学研究，第二部分是非均匀流场对短波破碎影响的动力学研究。

Under the assumption of linear ocean waves , and in the light of the theoretical framework about the probabilistic distribution of wave characteristics ( sun fu 1988 ) , several probabilistic distributions of wave characteristics that is necessary for the estimation of breaking probability and whitecap coverage are derived . afterwards , the models of breaking probability and whitecap coverage are set up with these distributions in addition to the kinematical criterion 在线性海浪假设下，基于孙孚( 1988 )关于三维海浪要素统计分布的理论框架，具体给出二维海浪波峰处质点水平速度和表观相速的联合分布等分布函数，在此基础上，根据运动学判据，分别建立起风浪破碎率和白浪覆盖率的理论模式。

On the other hand , various study in recent years about the kinematical breaking criterion show consistently that this breaking criterion persists under different conditions . therefore , in this thesis , a new set of models about breaking probability and whitecap coverage is set up using this breaking criterion 另一方面，近年来对于波浪破碎判据的研究表明，破碎的运动学判据是最可靠和最确定的判据，因此，本文采用运动学判据建立风浪破碎率和白浪覆盖率的统计模式。
