一类Stefan问题的渐近解

本文讨论了一类具有一般初值条件的Stefan问题.把研讨论板分成三部份,每一部份选用不同的时间尺度,然后用PLK方法或类多重尺度法求得每一部份的渐近解.最后,就此解进行了讨论并得出相应的结论.

The Asymptotic Solution of a Kind of Stefan Problem

In this paper, a kind of Stefan problem subject to general initial condition is studied. The slab considered is divided into three regions. There is a different time scale in each one. By means of PLK method or like multi-scales method, the asymptotic solution of each one is obtained. Finally we discuss the asymptotic solution and draw some conclusions.
