Abstract
Sufficient and (or) necessary conditions that can guarantee the PDAOR-metho d and the PDUAOR-method to be well-defined are presented in this note. This further weakens the convergence conditions about these two methods. Moreov er, some useful properties about the block matrices involved in these metho ds are investigated.
