| 中文摘要: |
| 本文提出了一种分析瞬时投放示踪剂条件下的一维河流水团示踪试验数据的新方法。该方法利用2个观测断面的示踪剂浓度观测数据，确定河流纵向离散系数、河流断面平均流速与释放参数等水质参数，并能够根据一级反应速率常数的计算结果判断示踪剂是否为惰性。通过实例应用表明，与利用直线图解法确定河流纵向离散系数相比较，新方法不仅能同时分析2个断面的观测数据，能够在预先不知示踪剂是否为惰性的情况下进行判断，而且具有计算结果可靠，计算过程比较简单、易于应用等特点。 |
| 英文摘要: |
| A method for determining 1 Ｄ river longitudinal dispersion coefficient, sectional average velocity and other water quality parameters according to the observation data of tracer concentration obtained from two river sections is suggested and the inertia characteristic of tracer can be identified according to the calculation result of first grade reaction constant. The application example shows that the proposed method is better than the linear graphic method and possesses the advantages of simultaneously analyze the observation data obtained from two sections and can judge whether the tracer is inertia or not. The calculation procedure is simple. |
