广义扩散过程带有两个自由端点的奇摄动自由边界问题

A SINGULAR PERTURBATION FREE BOUNDARY PROBLEM FOR A GENERALIZED DIFFUSION PROCESS INVOLVING TWO FREE TERMINAL POINTS

利用一个简单的自由边界问题的解构造出一个更为复杂的问题的解,而这个解可以描述广义扩散过程,并为其数值计算做好理论上的准备。

We construct a more complex solution by use of a relatively simple solution for afree boundary problem. The solution can describe generalized diffusion process andmake up theoretical base for numerical calculation.
