摘　　要：运用饱和信息维的增减技术对信息获取子空间进行结构上的剖分,将饱和信息维的"值"的获取分解为"白"与"灰"两部分,用饱和信息维列作为因子列来构造灰色关联空间,用关联序来描述信息之间的相关联程度,得到信息资源聚焦的一种新的数学模型。The increasing or decreasing technology of the saturated information dimension was applied to decompose and analyze the structure of information acquisition subspace one,and the acquisition of the value of saturated information dimension was divided into two parts—White and Grey. The saturation information dimension was used as the correlative order,applied to describe the grey correlative space,and the correlative oder was used to describe the correlative degree between information,thus obtaining a new mathematical model focusing on information resource.
