摘要
通过查阅国内部分数学分析教材和部分国外教材,指出某些教材中极限和连续定义存在的缺陷并加以比较和分析,对δ的取值范围进行了重新界定,给出改进的极限和连续的定义.
By consulting a large majority of domestic course books and several foreign course books, indicates some defaults in definition of limit and continuity in the books. Compares and analyzes the defaults, redefines the value range of δ, and gives improved definition of limit and continuity.
