| 摘 要： | 构造的单点迭代和ＭＧ倒排文件，是实现自适应性完全多重网格有限元方法 （ＡＦＧＦ ＥＭ）的基础。单点迭代是一种适用于局部校正的平滑过程，具有局部校正功能 和整体收敛性。ＭＧ倒排文件是一种适用于管理多层次剖分信息和迭代信息的数据结构， 具有适用于自适应加细和多重网格迭代的优点。

| Abstract: | Two aspects on the implementation of adaptive full multigrid FEM are discussed, As a local correction oprator for smoothing process, a single point iteration is constructed. It is also shown that the iteration has global convergent property. MG inverted file is a kind of data structure suitable to the management of informations of iteration and multi-level mesh, which has the advantage of being used for adaptive local refinement. |
