多元函数连续性的判定

Study of Proving Continuity of Multivariable Functions

从多元函数的连续性定义出发，给出判断多元函数连续的一些命题。这对在校大学生尤其对立志考研的学生来说，学习多元函数连续这一内容有着重要实际意义。

From the definition of the continuity of functions with several variables, some propositions and theorems for proving the continuity of functions with several variables are proposed. For college students, especially those who are dedicated to go on to postgraduate study, handling methods of proving continuity of multivariable functions is significantly meaningful.
