摘要
主要讨论经典集、模糊集和可拓集之间的关系，及可拓集的交、并关于否变换的可拓域和稳定域如何用原变换来表达，并导出可拓集之并、交的可拓域和稳定域的几个性质。
The relation among the set, the fussy set and the extension set is to be discussed. The extension region or the stable region to the negative transformation is expressed with the intersection or union of the extension region or the stable region to the primitive transformation. In addition, some properties on the extension set is shown.
