摘　　要：函数的连续性、可导性、可微性是高等数学中的重点、难点内容.运用二元函数连续、可导、可微的概念及相关知识,对二元函数的连续性、可导性、可微性进行了讨论,给出了与一元函数的连续性、可导性、可微性的区别与联系.The continuity, differentiability and differentiability of the function in higher mathematics are major and difficult content. This paper uses binary function continuous, differentiable, differentiable concepts and knowledge, the continuity of the binary function, conductivity, can differentiability discussed with the continuity of the function of one variable, differentiability, differentiable difference and connection.

关 键 词：二元函数 极限 连续性 可导性 可微性
