直线图解法在分析河流水团示踪试验数据中的应用

The Application of Linear-Schematie Met-hod to the Analysis of Watermass Traeing Ex-periment Data in River.

在示踪剂的一级反应速率常数K_1不为零的条件下,将反映水团示踪试验中示踪剂浓度变化规律的解析表达式进行适当变化,得到一直线方程。该方程的自变量和因变量中仅含有原始观测数据,直线常数中含有K_1、D和u三个参数。故在通过直线图解法或线性回归法求出两常数后,在K_1与u中有一个为已知时,即可求出另外两参数。

A linear equation can be deduced by changing, properly, the analytic representation reflecting the variation of tracer's concentration in water mass tracing experiment under the condition that the first-order reaction rate constant (K1) is not equal to zero. Only the original observed data are included in the independent and dependent variables of the equation and three parameters (K1, D, U) are included in the linear constant. Thus, after knowing two constants by using linear-schematic method or linear-regression method, the other parameters can be obtained if either K1 or U is known.
