摘　　要：给出了一个将孔口水流自由边值问题变换为拟线性椭圆型方程固定边值问题的方法．得到的固定边值问题容易用差分法离散．用迭代法求解。数值例子表明这个方法是简单有效的．A method,which transforms the free boundary problem of flow through an outlet into the fixed boundary problem of quasilinear elliptic equations,is given in this paper. It is easy to be discretized with different method and to be solved with iterative method for the fixed boundary problem. The numerical solution is effective and simple by numerical experiments.
