摘要
ε的"任意性"和N的"无穷性"是理解数列极限ε—N定义的关键所在,从两个诡辩问题实例出发阐述了ε—N定义中ε的"任意性"和N的"无穷性".
＂Arbitrariness＂ property ε and ＂ infinitary＂ property of Nare key points to understand the definition of limit of a sequence. The present paper expounds both ＂ arbitrariness＂ property of ε and ＂infinitary＂ property
v of Nbased on two sophistic problems.
