【Abstract】 Taking the difference minimum of the tracing agent theoretical value and the practically observed value as the object function, using the method of linear approximation, the paper transforms the linear optimum problem to a linear one. Adopting the one dimensional searching method, it can determine the optimum solution. Also, it applies the method to a case history. After comporison, it manifests that when the linear approximation method is used to determine the groundwater polluted matter transportion hyarodynamic parameters, it possesses the characteristics that the required data is few and the result is reliable. Thus, it has a certain practical value.更多还原
