【摘要】 从地球流体力学和热力学的基本方程出发 ,概述湍流二阶闭合的基本过程及闭合模型的实用简化 ,从而推广应用到生态动力学模型方程的二阶湍封闭过程中。本文给出了海洋浮游生态系统连续介质动力学模型方程的湍流二阶闭合过程的推导 ,在此基础上进行了简化 ,最终以 8组两两联立代数方程的形式表达了生态动力学二阶相关项的关系。本文还就湍流二阶闭合模型方程简化过程的若干问题进行了讨论。更多还原

【Abstract】 The basic processes of turbulence cl osure and its practicable simplification were summarized from the basic equation s of geophysics and thermodynamics, which was generalized to processes of closin g the equation set of ecosystem dynamics model. The second order closure of equa tions in the dynamics model for marine plankton ecosystems was formulated and it s simple formulation that second order relative terms were expresses by eight sy stems of two algebra equations was suggested thereby. Several problems in simpli fication of second order turbulence closure were discussed.更多还原
