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
在線性海浪假設下,基於孫孚( 1988 )關於三維海浪要素統計分佈的理論框架,具體給出二維海浪波峰處質點水平速度和表觀相速的聯合分佈等分佈函數,在此基礎上,根據運動學判據,分別建立起風浪破碎率和白浪覆蓋率的理論模式。The problem of non - classically damp, after the structure ' s damp and linear water ' s damp are added up, are solved by way of complex mode transformation, and the dynamic responses of a offshore platform are studied under the circumstances of thinking about the mutual effect or not

本文在總結概述前人關于boussinesq方程波浪數學模型研究進展的基礎上,主要做了以下幾點工作:從質量守恆方程和euler方程出發,以某一水層處水平速度矢量作為獨立變量,推導出包含底摩擦耗能、波浪破碎效應和子網格湍流效應的改進型boussinesq方程。Wave off into shallow waters, seabed by the friction effect change steep wave front, trough ice, water points trajectory showed reciprocating flow, but also to the shore into the flow speed usually return rate greater than offshore, the net result of sediment at the bottom to the shore handling, and was the shock waves on the shore with the water current - riviera online accumulation
外海波浪傳入近岸淺水區,受到海底的摩擦作用,波鋒變陡、波谷變緩,水質點運動軌跡呈現往復流動,而且向岸進流速度通常大於離岸迴流速度,導致底部泥沙凈向岸搬運,並被激岸浪的上沖水流帶至海濱線上堆積。Physique conditions of freshmen in 2002 grade, 2003 grade, 2004 grade when they entered colleges were tested and the results showed that figures of college freshmen in wuhan area were good ; function of heart and lung were decreasing significantly ; physical quality and sport ability were not balanced and stable
