二元函数连续性条件之探析

摘要

Aboute continuity judgements condition of two variables functions was analysed in detail. Some key problems of the question were emphasized, and several vague knowledge easy to be arised for students was put right, and presents some sufficient condition for continuity and its extended form.%对二元函数连续性判定条件给出了详细分析，强调有关问题的关键点，纠正了常见的模糊认识，得到一系列连续性充分条件及其推广形式．
