中文摘要：

在气压的压力下面，在好含水土层的系统的地下水流动是一种流体力学的联合问题。使用地上凿穿上的条件围的流动边界和水压力平衡在内并且在外面在气压的压力 BP 下面调节地上凿穿墙，浇得好的水平变化的一个分析答案在这份报纸被建议了。明确的表达证明 BP 系数与时间增加并且趋于到 BP 常数。BP 系数的变化随着时间的过去仅仅取决于 transmissivity T 的比率到井半径摆平的 r2，，并且在 BP 与变化没关系。BP 常数仅仅联系到装载效率 B 的含水土层，并且与含水土层 transmissivity 和井半径没关系。BP 系数变化随着时间的过去与从 Nanxi 井的测量数据的分析在分析明确的表达一致。随着时间的过去基于 BP 系数变化，一个参数评价方法被使用 Nanxi 很好在它的应用程序建议并且讨论到含水土层 BP 常数或 B 和 transmissivity 的评价数据。

英文摘要：

Under barometric pressure, groundwater flow in well-aquifer systems is a kind of hydromechanical coupling problem. Applying the flux boundary conditions on borehole wall and water pressure equilibrium conditions inside and outside the borehole wall under barometric pressure （BP）, an analytic solution to well-water level changes has been proposed in this paper. The formulation shows that the BP coefficients increase with time and tend to BP constant. The Change of BP coefficients over time depends only on the ratio of transmissivity （T） to the well radius squared （ r2, ） , and has nothing to do with the change in BP. The BP constant only relates to aquifer loading efficiency （B）, and has nothing to do with the aquifer transmissivity and well radius. The BP coefficients＇ change over time in the analytic formulation is consistent with the analysis of measured data from the Nanxi wells. Based on the BP coefficient changes over time, a parameter estimation method is suggested and discussed in its application to the estimation of the aquifer BP constant （or B） and transmissivity by using the Nanxi well data.
