摘　　要：对给定的集合 E,可导出若干集合。把这些导出的集合看作是对集 E实施集合运算所得。用集合运算的观点给出由集 E导出的集合的定义。讨论了这些集合运算的性质 ,并给出了若干实例 。For given set E many sets can be led. Those sets are considered operating to set E. Then it gives out some definitions of sets for E, which is given using views of set operations. Property discussions of set operations and some examples are put forward to show the application in proving specific problems.
