| 摘 要： | 根据基本的扩散方程，以污染物质输入量为已知条件，给出了一种近区稀释的半解析解。该半解析解摆脱了流速是单向的、持续的和定常的条件限制，反映了近区稀释在以潮流场为背景场的状态下，随时间的可变性。

| Abstract: | Based on the diffusion equations, we get a semi-analytic solution of further transport of waste water. In the solution, the condition of the mass input of waste water is known. The most important difference between this solution and the conventional solution lies in the background velocity field. The background in our solution is a tidal current field as a function of time instead of being constant in the conventional solution. Therefore our solution decribes the variability of further transport as a function of time. |
