摘要：
We show the lower semicontinuity of the family of pullback attractors for the singularly nonautonomous plate equation with structural damping u(tt) + a(t, x)u(t) + (-Delta)u(t) + (-Delta)(2)u + lambda u = f(u), in the energy space H-0(2)(Omega) x L-2(Omega) under small perturbations of the damping term a.
