摘　　要：In this article, we introduce and characterize approximate duality for g-frames.We get some important properties and applications of approximate duals. We also obtain some new results in approximate duality of frames, and generalize some of the known results in approximate duality of frames to g-frames. We also get some results for fusion frames, and perturbation of approximately dual g-frames. We show that approximate duals are stable under small perturbations and they are useful for erasures and reconstruction. 关键词：HILBERT空间对偶框架小扰动两重性
