摘 要：Abstract We present a theory of two-level additive Schwas preconditions for plate elements. It is applicable to the cases where the finite element spaces on the two levels are(I) conforming and nested,(II)conforming and nonsked, and (III) nonconforming and nonnested. The condition number of the preconditioned system is independent of the mesh sizes and the number of subdomains in the case of generous overlap.
