摘　　要：根据蔡文提出的可拓集合的新定义,给出了可拓集合的包含、并、交、非运算的新定义,并讨论了有关运算性质,进而获得可拓域与稳定域的几个交并运算结果.According to the new definition of extension set given by Caiwen, new definitions of its inclusion, joining, intersection and negation operations are given. Operations of the extension set and its property are discussed. Finally, some results of intersection and joining operations on extension ranges and stable ranges are obtained.

关 键 词：可拓集合运算 可拓域 稳定域
