中文摘要：

为了研究Hibert空间中近似标架的性质，基于Hibert空间中通常标架的理论，运用对偶标架的构造方法，引入了近似标架对偶标架的概念，给出了近似对偶标架的2个明确表达，得到了近似对偶标架的一些扰动结果．

英文摘要：

Based on the frame theory of Hilbert space and by using the method of construction of dual frames, the notion of approximative dual frame was introduced, two explicit expressions of an arbitrary approximative frame were established, some perturbation results of approximative dual frames were obtained.
