摘　　要：知识的属性扰动引起知识规律的变化,这些属性扰动知识规律具有链式特征;利用S-粗集,给出知识规律、属性扰动的知识规律和扰动度的概念,并对知识规律与属性扰动的知识规律进行了讨论,提出了属性扰动知识规律的链式定理.The changing of knowledge law is caused by the attribute disturbance of knowledge,and the knowledge law of attribute disturbance has chain characteristics. By employing S-rough sets, this pa＇per presents the concept of the knowledge law,the knowledge law of attribute disturbance and the concept of attribute disturbance ,and then the two laws are discussed. Consequently, the chain theorem of attribute disturbance knowledge law is proposed.

关 键 词：知识规律 属性扰动 扰动度 属性扰动知识规律的链式定理
