对单变量连续的二元函数的连续性

The continuity of a binary function with continuous attribute for single variable

从连续的概念出发,深入探讨一元与二元函数连续定义的本质,通过质疑和释疑,研究了单变量连续的二元函数的连续性问题,获得一些有意义的结论.

With the concept of continuity,discussed in detail the definition of the continuity on both unary and binary functions in essence.Researched the continuity issue with respect to the binary function with continuous attribute for single variable through questioning and explanation,obtained some meaningful conclusions.
