| 中文摘要 |
| 为获得洋河张家口-宣化段水体的弥散系数,用罗丹明B进行了示踪试验,简述了三次样条函数插值方法,并用该法处理了示踪试验数据,用一维扩散模型计算的纵向弥散系数为5.53m2/S.最后用二维模型进行检验,表明上述处理方法和系数是可靠的。 |
| 英文摘要 |
| In order to obtain dispersion coefficient in the Zhangjiakou-Xuanhua section of the Yanghe River, the trace experiment has been done by using rhodamine B. An interpolation method of triple-spline function is descnibed briefly and used to handle the expenimental data of dilution and diffusion in the Yanghe River. The dispersion coefficient calculated in accordance with one-dimension diffusion model is 5.53 m2/s and then has verified with two dimension diffusion model. The result sh-ows that the method mentioned above is correct and reliable. |
