摘　　要：Let A and B be quasisimilar operators. We describe refinedly the intersection relationsof the components of various essential spectra of A with various subsets of the essentialspectrum of B, and give an affirmative answer to a question posed by L. A. Fialkow.Let A and B be quasisimilar operators.
