一、前言目前,国内外都密切注视着海洋环境的污染状况。为了保护我国海洋尤其是港湾近海区域环境,必须大力开展积极研究污染物质在海洋中的输运和扩散,以便更好监测、预报和控制海洋污染状况。研究海水中污染物的输运和扩散有三种途径:一是数值模拟,二是物理模型实验, I. Foreword At present, the pollution situation in the marine environment is closely watched both at home and abroad. In order to protect the environment of our oceans, especially in the harbor and offshore areas, we must energetically study the transport and spread of pollutants in the oceans so as to better monitor, forecast and control the marine pollution. There are three ways to study the transport and diffusion of pollutants in seawater: one is numerical simulation; the other is physical model experiment;
