摘　　要：B. Sz-Nagy and C. Foias introduced the concept of quasisimilarity in 1967. Since then, the quasisimilarity of operators has become an important research problem in the theory of operators and a lot of attractive results have been obtained. But, as regards intersection relations between some subsets of the spectrum σ(A)and those of the spectrum σ(B), where A and B are quasisimilar operators, comparatively few results have been delivered.
