| 摘 要： | 运用概念的闭标记研究了强协调决策形式背景的核心属性问题。通过概念的闭标记得到了判定强协调决策形式背景的协调集的方法，并且定义了计算约简集的函数，从而得到了约简集，最后通过简单的集合运算得出协调决策形式背景的核心属性。

| Abstract: | The core attribute of a strongly decision formal context by the closed label of a concept was studied .Using the closed label of a concept ,a method of judging a set whether if is a consistent set of the strongly decision formal context was given .Further ,a function of computing the reductions was defined , and the reduction set was obtained .Finally ,through a collection of simple set operations ,the core attrib-ute of the strongly decision formal context was achieved . |
