摘　　要：本文根据河流混合带污染物质的输运、变化过程,应用有限容积法求解二维动态水质方程,给出了潮汐河流废水岸边排放及江中排放情况下挥发酚二维浓度分布的算例.计算结果与实测结果吻合较好.与有限差分法相比,有限容积法具有物理意义明确、算法简单等优点.该法对进一步研究河流污染带的分布有一定的参考价值.Based on the transportantion and variety of pollutants in the river, the finite volume method is used to solve the unsteady two-dimensional convenction-dispersion eqaqtion. The approach is illustrated by modeling the two-dimensional distribution of concentration for volatile phenol in a tidal section of Yangtze River. A good agreement between the calculated and observed volatile phenol distributions is obtained. Compared with the finite difference method, this method has the features of cleavability in phys...
