摘　　要：连续和极限是数学分析的两大基石。初等函数的连续性(或分段连续)对中学生来说也是不言自明的,充分应用函数连续性这一性质可以方便地解决一些方程或不等式的问题,尤其是利用"相等"来解决"不等"的问题。Continuous and limit are two cornerstones of mathe matical analysis. The continuity of elementary functions is also selfevident for students, making full use of the continuity of the function can easily solve some equations or inequalities, in par tieular the use of ＂equal＂ to solve the ＂unequal＂ problem.

关 键 词：初等函数连续性应用
