摘　　要：本文主要研究了具有奇异振荡外力项和弱阻尼项的记忆型粘弹性发展方程。首先证明了在外力项和记忆核满足恰当条件时方程一致吸引子 Aε在空间H = H01(Ω)×H01(Ω)×M中的一致有界性, 进而证明了当ε→0+ 时一致吸引子的上半连续性。This paper is concerned with the development of memory viscoelastic equation with singularly oscillating external force terms and weak damping terms. First, we prove the consistent boundedness of the uniform attractor A" of the equation in H = H01(Ω)×H01(Ω)×M when the external force term and the memory kernel satisfy the appropriate conditions, and then the upper semicontinuity of the uniform attractor when ε→0+ is achieved.
