：含水层的透射率和蓄水性通常通过稳定或非稳定抽水测试数据的分析来确定。非稳态泵送试验分析的经典方法本质上大多是图形化的，因此在曲线拟合、插值以及读取图形和图表时容易出现判断错误。这里描述的方法不需要构建图表或使用图表和表格。使用非稳态时间下降场数据的回归分析来计算透射率和存储率。计算可以很容易地在手持计算器上进行。使用四个示例描述了该过程，并将结果与通过图形技术获得的结果进行了比较。结果表明，对于非渗漏自流含水层，该方法是 Theis 型曲线解或 Jacob 直线解的可行替代方案。然而，回归方法在自流含水层和地下水位含水层渗漏的情况下会出现问题。
: Transmissivity and storativity of an aquifer are usually determined by analysis of steady or nonsteady pumping test data. The classical methods of nonsteady pumping test analysis are mostly graphical in nature and are, therefore, subject to errors of judgment in curve fitting, interpolating, and reading graphs and charts. A method is described here which does not require construction of graphs or use of charts and tables. The transmissivity and the storativity are calculated using regression analysis of the nonsteady time drawdown field data. The calculations can readily be performed on a hand held calculator. The procedure is described using four examples, and the results are compared with those obtained from graphical techniques. It is shown that the method is a viable alternative to the type curve solution of Theis or Straight line solution of Jacob for nonleaky artesian aquifers. However, the regression method poses problem in the cases of leaky artesian and water table aquifers.
