Linear Regression Method for the Determination of both Longitudinal Dispersion Coefficient and Transverse Mixing Coefficient of River by instantaneous Dumping Tracer Test
瞬时源示踪实验确定河流纵向离散系数和横向混合系数的线性回归法

Starting from the equation for two-dimensional concentration distribution of instantaneous dumping, a linear equation Y=AT+B was mathematically deduced, in which variables Y and T can be expressed with e. c. and C2t, while coefficients A and B 31 e composed of parameters of Dx and Dy to be determined, longitudinal and transverse flow velocities of the river u and v as well as ;he coordinates of the observation point X and Y. Throughlinear regression, A and B can be determined from Ci and Ti, the observed experimental data. Then Dx and Dy can, be calculated by solving the equation.
