| 中文摘要 |
| 本文在实验室矩形平直明渠内,对横向混合系数的公式结构进行了探讨.在室内模型内做大量的示踪试验,获得63组实验数据,在此基础上确定了关于横向混合系数的准数关系式,并对该式作了分析.由室内模型所归纳的公式和结论,可为天然顺直河流横向混合系数的确定提供参考. |
| 英文摘要 |
| The formulary structure about transverse mixing coefficient of rivers has been studied at the laboratory model of straight rectangular open channel. In the model, a lot of trace experiments were performed so that 63 groups of data were obtained. On the basis of the experiments, the relation for transverse mixing coefficient was offered and analyzed. The empirical formulation and some conclusions induced by the model will provide reference for ascertainment of the transverse mixing coefficient in natural streams. |
