摘　　要：阐明在求函数极限的过程中用等价无穷小代换能使计算简化,同时还讨论了等价无穷小的适用范围问题．It was illustrated in this paper that in the process of calculating limits, the usage of equivalent infiuitesimal substitution could simplify the calculating procedure. Besides, the applied range of the equivalent infinitesimal was also discussed .

关 键 词：极限 等价无穷小 代换
