摘要
鉴于传统熵与时间无关 ,不能反映海 -气耦合机制下海浪场的基本属性———不可逆性 ,文章将非平衡信息论熵的概念引入海浪场的研究。依据海浪场相空间的Fokker Planck方程 ,首次推导出了非平衡信息论熵的熵平衡方程、熵密度、熵流密度、熵产生密度、广义力和广义力密度的具体表达式。
Seeing that the traditional entropy has nothing to do with time and can not reflect the basic property of sea wave field under air sea coupling mechanism,the concept of nonequilibrium information theory entropy is introduced to the study on sea wave field.The equilibrium equation of entropy and the specific expressions of entropy density,entropy current density,general force and general force density are derived for the first time.
