With this model, the pressure drop curve of well testing is interpreted, and mobility ratio, diffusionratio, sweep radius of each area and some other parameters are solved.
利用该模型可以对火烧油层注气井试井压降曲线进行解释，并求解流度比、扩散比以及各区的波及半径等参数。

Decreasing hydraulic conductivity and diffusion coefficient may delay the increasing rate of the concentration ratio at the base of a GCL.
结果表明，减小渗透系数和扩散系数可以有效减缓衬垫底部浓度比的增加速度。

Then, the concentration under different wind diffusion condition are analysized by using ground pollution mode so that the ratio of contribution to the total pollution limit is obtained.
