摘要：

A new class of inner-outer iterative procedures in conjunction with Picard/Newton methods based on normalized explicit approximate inverse finite element matrix techniques for solving sparse non-linear finite element systems of irregular structure is presented. Normalized explicit preconditioned conjugate gradient schemes, based on a class of normalized explicit approximate inverse matrix techniques, are given for solving non-linear boundary value problems. Applications on characteristic non-linear boundary value problems in two dimensions are discussed and numerical results are given.
