| 摘 要： | 本文首先从动态水质模型出发，将该方程组对潮周时均化，并将所得结果与稳态水质模型进行比较，从理论上找出了这两组方程的等值条件，提出了潮汐河道中采用稳态模型需要满足的两个条件。文中还引入并推求了影响稳态模型计算可靠性的河道潮汐加速度，建立了潮汐加速度变化对水质计算参数影响的估算式，对用稳态模型计算潮汐河道中污染物浓度所产生的误差提出了一种分析计算方法。

| Abstract: | The dynamic model of water quality was averaged over tidal period and the results obtained were compared with the steady-state model. Equivalent conditions of the two sets of equations were found theoretically. Two condition were proposed which should be satisfied when using steady-state model in the tidal river. Tidal acceleration in the river which will influence the calculation reliability of steady-state model was introduced and determined. The experession for estimating the affect of changing tidal acceleration on parameter of water quality calculation was established. An analytic method computing pollutant concentration in the tidal river by using steady-state model is proposed. |
