摘要：
In this paper, we get some new characterizations of pseudo-similarity for semi-groups. As an application, we deduce that if R is a QB-ring then asimilar or equal tob in R if and only if for all n is an element of N, there exists u is an element of R-q(-1) such that a(n) = ub(n)u(q)(-1) and b(n) = u(q)(-1)a(n)u.
