| 摘 要： | 简略地介绍了双重介质含水层模型；推导出引潮力作用下双重介质含水层中渗流运动的偏微分方程；将此泛定的方程与潜水的Boulton方程进行数学类比，从而得出一个新的迟后给水项，为解释固体潮致井水位振荡相位滞后现象奠定了物理基础；通过对该泛定方程的分析，还发现该迟后给水项与深部含水层中存在的一种潮汐液流振荡现象有关．

| Abstract: | A model of double medium aquifer is briefly introduced in this paper, a partial differential equation about seepage motion derived by the tidal stress i n the model layer is deduced. Compared this equation with Boulton equation used in the unconfined aquifer, a new lagging supply water term is obtained, which establish the physical basis for interpreting the phase delay phenomena of well water level caused by the solid tide. By analyzing the partial diffe rential equation, it is found that this lagging supply term is rela ted with the fluctuation of tide occurred in the deep aquifer. |
