摘要：
The Authors show-that the global matrix in the finite element integro-differential formulation of two-dimensional skin effect problems can be partitioned into the sum of a sparse mw trix. and a product of two equal arrays for each conductor of the mullticonductor system. This partition allows both a great memory saving and a drastic reduction in the conjugate gradient solution time.
