摘　　要：函数单向S-粗集对偶生成的F-粗积分具有一系列动态特性,在此基础上提出了F-粗积分的度量——F-粗扩张度与F-粗扩张率的概念及属性施效识别原则。函数单向S-粗集对偶的变化程度不仅可以得到量化,而且对系统在离散的时间区间上的S-粗状态也可进行检测-识别。这是一个新的研究方向。F-rough integrals generated by the dual of function one direction S-rough sets have a series of dynamic characteristics,based on which the measurements of F-rough integrals-F-rough expansion degree and F-rough expansion ratio are defined,and the principle of the attribute effect recognition is obtained.So the changing extent of the dual of function one direction S-rough sets can be described with numbers,meanwhile,the system S-rough state on some discrete time sections can be detected and recognized.This is a new research direction.
