| 摘 要： | 《高等数学》教材中函数极限limf（x）=A的几何解释．与曲线的水平渐近线的几何解释存在着差异。笔者指出：二者的几何解释是一样的，同时建议，在《高等数学》教材中应该全面介绍曲线的渐近线的精确定义（包括其求法），这样做。可以使学生正确而全面地理解、掌握曲线的渐近线的概念，对学生做初等函数的图形也是有帮助的。

| Abstract: | There exists difference between geometric interpretation of limit function and geometric interpretation of curvilinear horizontal asymptote in the textbook of higher mathematic.The paper points out that the two geometric interpretation is all the same.At the same time,the author suggest that it’s ought to give overall introduction of precise definition for curvilinear horizontal asymptote(including it’s solving method).By this means,it’s useful to understand and master the concept of curvilinear horizontal asymptote correctly and fully and draft elementary function for the students. |
