摘要
在示踪剂的一级反应速率常数Ｋ１及河流平均流速Ｖ均未知的条件下，将反映河流示踪试验中示踪浓度变化规律的解析表达式进行适当变化，得到二元线性方程。该方程的自变量和因变量中仅含有原始观测数据，线性常数中含有Ｋ１、Ｄ和Ｖ三个参数，故在通过最小二乘法求出线性方程中三个常数之后。
A binariate linear equation can be deduced by changing the analytic representation reflecting the variation of traces concertration in water-mass tracing experiment under the condition that the first-order reacting rate constant (K 1) and the river flow velocity (V) are not known. Only the original observed date are included in the independent and dependent variables of the equation, and three parameters (D,V,K 1) are included in the Linear constants, Thus, after knowing three constant by using least-square method, the three parameters (D,V,K 1) can be obtained.
