摘要 证明了非自治吊桥方程当非线性项g u(,t)和外力项f x(,t)都与时间t有关且g u(,t)平移有界时解的渐近性行为,并由此获得了方程在H2 0(,L)∩H100(,L)×L2 0(,L)中的拉回D-吸引子的存在性. We prove the asymptotic compactness of process for the non-autonomous suspension bridge equations with a nonlinearity g u(,t) and a forcing termf x(,t),and g u(,t) is translation bounded.Furthermore,we obtain the pullback D-attractor in H2 0(,L)∩ H100(,L)×L2 0(,L).
