摘要：

For given matrices A and E which are n x n matrices and B = A + E, we discuss upper bounds for parallel to B(#)parallel to, parallel to BB(#)parallel to, parallel to B-# - A(#)parallel to/parallel to A(#)parallel to and parallel to BB# - AA(#)parallel to/parallel to AA(#)parallel to, also a lower bound for parallel to B(#)parallel to is derived.
