摘　　要：F-粗积分是函数单向S-粗集上的一个积分对,基于F-粗积分引入面积覆盖度和边界厚度概念。讨论了当有外来属性迁入函数单向S-粗集的属性集时,面积覆盖度、边界厚度等的一系列变化,给出其动态变化规律。面积覆盖度和边界厚度把对F-粗积分的讨论由定性过渡到定量。F-rough integrals were composed with one pair of the integrals, which was used to introduce the concepts of the degree of covered area and boundary thickness. The characteristics of the area were discussed and the dynamic law was given. The degree of covered area and boundary thickness turns the discussion about F-rough integrals from quahty to quantity.
