摘要
文中将描述瞬时投放示踪剂，一维流动二维地下水弥散过程的解析解进行了适当数学变换，得到一个二元线性回归方程。该方程中的自变量和因变量中仅包含着试验数据，回归系数中包含着待求参数。通过对两个观测孔中的观测数据进行分析，可以得出五个包含待求参数的方程。由这些方程，推导出了计算ａＬ、ａＴ、ｕ、ｎｅ和λ五个参数值的公式。线性回归法的主要优点为在示踪剂不论是否为惰性的情况下均可以应用。
Abstract With suitable mathematical transformation in this paper, the analytical solution to discribing one-dimensonal steady flow and two-dimensonal ground-water dispersion in the case of instantaneous injection of tracer has been changed into a linear equation with two dependent variables. The independent variable and the dependent variables in this equation are only the functions of the test data, and the regresion constants are those of the parameters to be detdrnined. With analyzing the data in two obversation wells, five equations to compute the values of a L、a T、u、n e and λ can be achieved. The main advantage of this method no matter if the tracer inertial or not.
