摘要：In this article we prove that if P = {P(s,t)}s≥t≥0 is a self adjoint and strongly q-periodic continuous evolution family of bounded linear operators acting on a complex or real Hilbert space H then P is uniformly exponentially stable if for each unit vector x ∈ H the integral ∫n∞ ϕ() ds is bounded, whereϕ :R := [0,∞) → R+ is a non-decreasing function such that ϕ(0) = 0 and ϕ(s) >0 for all s ∈ (0∞) .
