摘要：
This work describes a two-dimensional analytic solution of a nonlinear diffusion equation. The interface of this solution is a half line, whose origin is a singular point that advances at constant velocity. The regions that lie on both sides of this line are gradually welded behind the singular point. (C) 2000 Elsevier Science Ltd. All rights reserved.
