摘要
本文构造了一种求解奇异摄动抛物型方程的渐近数值方法,该方法不需要在边界层附近取很细的网格步长。同时提出了一种用数值的方法来近似地确定边界层宽度的方法,
In this paper,an asymptotic numerical methOd fOr the singu laly perturbed problem of parabolic differential e-quations is proposed;which does not need to take very small mesh size from the mghbourhood Of the boundary layer.And amethod for determining approximally the width of the boundarY layer is provided.
