摘　　要：ε-语言是标准极限理论教学中的难点,为弄清难点所在,将标准极限理论的ε-语言定义中所涉及的某些问题进行分解,通过测试和调查,分析学生在学习极限理论、掌握其语言表述和理解逻辑关系时存在的认知障碍,以期从根本上改进相关内容的教学.ε-language was the main difficulty in standard limit theory teaching. In order to find out the origin of the difficulty, all respects of questions, which were involved in standard limit theory were decomposed, and through test and investigation, concrete obstacles which were met by the students in the course of learning the theory, mastering the language expression and understanding the logical relations were analyzed. By doing this, improving the relative content＇s teaching essentially was expected.
