摘　　要：动态系统规律知识是规律对象(规律外延)与规律属性(规律内涵)的统一体,利用变异单向函数S-粗集与变精度粗集提出变精度变异单向函数S-粗集的概念和它的F-结构,给出变精度变异单向函数S-粗集的有关性质定理和推论,对此进行了讨论。应用变精度变异函数单向S-粗集对动态系统的内涵规律的精度进行数据挖掘。容易挖掘-发现出动态系统中规律的相关性和规律的近似决策规则。变精度变异单向函数S-粗集为研究动态系统规律提供了一种新的途径。The knowledge of dynamical system law is the unity of law object （law extension） and law attribute （law connotation）. It presents the concept of the one -direction variation function S-rough sets of the variable precision and its F- structures by using function S-rough sets of the variable precision rough sets and its property theorem and its corollary, and explains them. By mining the data of the precision of connotation law of dynamical system with one-direction variation function S rough sets of the variable precision,it is easy to discover and find the relativity of law and its approximate decision rule in dynamical system. The one-direction variation function S-rough sets of the variable precision presents a new method to research dynamical system law
