摘　　要：在信息获取科学的基础上,用区间灰数来描述信息维的取值域,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,用区间灰数的运算来表述信息子空间的基本操作,并讨论了一类灰数下的信息含量,得到信息资源聚焦的一种新的聚焦子空间的形式化描述和有关数学运算性质。Be based on information acquisition science, the interval grey data is used to describe the domain of informarion dimesion, and the increasing or decreasing technology of the saturated information dimesion are applied to decompose and analyse the structure of information acquisition subspace one, and the operation of interval grey date is used to describe basic manipulation of information subspace. Then,the paper discusses the amount of information of a type of grey data , and obtain a new information resource focusing method of formally describing focussing subspace and quality about mathematics.
