一、前言海洋扩散的研究最初建立于分子扩散方程的基础之上,以后又发展到Fickian扩散方程。Richardson扩散方程及其它多种模式。一个方程的解,能否刻画实际情况,主要取决于初始条件和涡动扩散系数K,而K值又依赖于扩散团的尺度,扩散时间t和平均能量耗散率G等因素。最近三十年来,扩散的理论研究、试验研究、数值模拟等都得到迅速发展。其中有 I. INTRODUCTION The study of ocean diffusion was first based on the molecular diffusion equation and later on to the Fickian diffusion equation. Richardson diffusion equation and many others. The solution of an equation depends on the initial conditions and the eddy diffusion coefficient K, which in turn depends on the scale of the diffusion group, the diffusion time t and the average energy dissipation rate G. In the recent three decades, theoretical research, experimental research and numerical simulation of proliferation have all undergone rapid development. Including
