摘要： 对动态约简的思想进行了阐述，详细分析了其中子表族抽取的有关问题。根据正态分布的区间佑计推算对所有动态约简都适应的F族抽样值，并在此基础上将约简精度系数纳入了F族的抽样考虑范畴，提出了一种计算F族范围的方法，发展并完善了对F族抽样计算的理论思想。
关键词: 动态约简，F族，抽样计算
Abstract: This paper formulated the dynamic reduct model and analyzed the withdrawing of sub-table family F. We calculated the sub-table family according to space estimation of normal distribution and proposed one method of calculating the size of dynamic reduct sulrtable family F based on the reduct accuracy coefficient, which developed and completed the idea of sampling sub-table family F.
Key words: Rough set, Dynamic reduct, Sub-table family F, Sampling computation
