摘　　要：The main purpose of this paper is to establish some new sufficient conditions under which shift-invariant systems become frames in L2（Rn）. As applications, we obtain new results for Gabor frames.The main purpose of this paper is to establish some new sufficient conditions under which shift-invariant systems become frames in L2（Rn）.
