摘 要：本文引入了廣義Banach框架的概念，研究了該框架所對(duì)應(yīng)的框架算子的特點(diǎn)，利用框架算子給出了一個(gè)廣義Banach框架判定的充要條件。并且對(duì)該框架穩(wěn)定性進(jìn)行了研究，推廣了Hilbert空間中的廣義框架與可測(cè)空間上定義的（Ω，μ）框架穩(wěn)定性的有關(guān)結(jié)論。

Abstract：In this paper，we introduce the conception of Generalized frames in Banach space and study the proprety of the frame operator.A necessary and sufficient condition for Generalized frames is given.Besides，we study the stability of Generalized frames in Banach space and the results of Generalized frames in Hilbert space and （Ω，μ） frames in a measurable space are generalized.

Key Words：Generalized Frames in Banach Space；Frame Operator；Stability
