Abstract: Smooth（normal） subgroup is constructed by the rough subgroup of a group；and a rough（normal） subgroup is induced by the smooth group based on group and its normal subgroup.The relations between them are obtained.
Key words: smooth subgroup, upper rough subgroup, fuzzy equality
摘要： 在群中通过其粗糙（正规）上子群构造了smooth（正规）子群；通过群及其正规子群诱导的smooth（正规）子群进一步构造了粗糙（正规）上子群，并给出它们之间的联系。
关键词: smooth子群, 上粗糙子群, 模糊相等
