摘要
本文研究带有抽取的非饱和流动中出现的一个非线性边值问题．利用互惠变换及HopfCole变换将问题化为一个移动边界问题，进而获得了Fourier级数解．
In this paper a nonlinear boundary value problem which arises in an unsaturated flow with extraction is studied. A reciprocal transformation and the Hopf-Cole transformation are employed to transform the nonlinear boundary value problem into a moving boundary problem for which the Fourier series solution is obtained.
