In this paper we shall study properties of a class of abstract dynamic system. Using the decomposition method of Hilbert space, we give an explicit expression of spectrum of main operator and C0-group, then obtain the property of abstract dynamic system by the perturbation of bounded linear operator. As an application we investigate integro-differential equation arising in transport theory.
