A positive answer to the open problem of Iorgulescu on extend weak-R 0 algebras and R 0 algebras to the non-commutative forms is given. Some properties, the noncommutative forms of the properties in weak-R 0 algebras and R 0 algebras, are investigated. The simplified axiom systems of weak-pseudo-R 0 algebras and pseudo-R 0 algebras are obtained.
