摘要
本文处理带有两种流体的轴对称的一个自由边界问题，其中在渗流区域的上部是油，下部是水，这是同时取油注水的一个数学模型．下面，我们将用复分析方法求出此自由边界问题的一个解，并证明其解的唯一性．
This paper deals with a free boundary problem in axisymmetric filtration withtwo fluids, where the supper level in the filtration domain is the oil and lower level is thewater, this is a mathematical model of oil extraction and water flooding simultaneously. Inwhich, describing the model is a free boundary problem for elliptic complex equation. In thefollowing, we shall use the complex method to find a solution of the free boundary problemand to prove the uniqueness of its solutions.
