本文试图导出在潮流和同阶准定常流共同控制下,对流为主或与湍扩散同阶的近海系统中的湍封闭长期输运方程式.通常以下列对流-扩散方程来描写近海或河口中浓度c的输运过程:
In this paper, we try to derive the turbulent closed-term transport equation in a coastal system dominated by convection or in the same order as turbulent diffusion under the common control of tidal current and same-order quasi-steady flow. The convection-diffusion equation is usually used to describe the concentration in offshore or estuarine c transport process:
