越流含水层系统在我国分布十分广泛，但国内有关越流含水层系统的地下水污染模型尚未见报导。为建立越流含水层系统地下水污染的数学模型，本文导出了包括越流项和井流项的溶质运移方程。 The more the aquifer system is distributed in our country, but the groundwater pollution model of the aqueduct in China has not been reported yet. In order to establish the mathematical model of groundwater pollution in the over-flow aquifer system, the solute transport equation including the over-current and well-flow terms is derived.
