Abstract:

In this paper, a moving-boundary problem occurring under the acidifying was discussed, which was transformed into a coupled piroblem of an initial-boundary value problem of nonlinear parabolic equation and an initial value problem of di13'erential equation. Then, the full discrete scheme was given.

Key words: moving--boundary problem, coupled prob-lem, full discrete scheme
