| 摘 要： | 介绍了应用有限单元法预测计算河道较平直，水流稳定河流中污染物浓度分布的二维平面数学模型，该模型具有应用方便，计算迅捷等优点，计算中无须先知道排放口污染物掺混浓度，能直观地反映有多个排放口的河流中的污染物浓度分布的情况。

| Abstract: | Two dimensions mathematical model is shown, in which a finite element method is used. The model can be applied conveniently and rapidly to calculate the contaminant density in a straight river with steady current. The contaminant mixing density near the discharge inlet need not be known before the calculation. Much more advantage dosed the models have to calculate in the river with multiple discharge inlets. |
