摘　　要：应用质量守恒原理 ,通过适当的数学推导 ,将描述一维水团示踪试验的解析表达式转化为一直线方程 .在进行数据分析时 ,只要按文中提出的步骤进行数据转化 ,便可采用线性回归法或直线图解法计算直线常数 ,从而能够确定出河流纵向离散系数 D.最后 。By applying the conservation law of mass and with appropriate mathematical deduction, the analytical expression for describing the variation of tracer's concentration of one dimensional river stream has been transformed into a linear equation, of which the dependent variable is the function of test, the independent variable is the function of the observation time and the liner constants include longitudinal coefficients. Hence the test data are transformed by the method proposed, the linear regression method or linear regression method or linear schematic method can be used to determine the values of the linear constants and finally the value of D can be estimated.
