| 摘 要： | 无穷小量的阶刻画了无穷小量趋于0速度的快慢,对计算无穷小比值型极限起着至关重要的作用,本文通过定义阶函数,讨论了在加减因子中利用等价无穷小代换的条件,得到了一些结论,最后讨论了0这个特殊的等价无穷小.

| Abstract: | The order of Infinitesimal portrays the speed of infinitesimal tends to 0,it plays a vital role to calculate the limit of infinitesimal ratio.By defining order function,this paper discussed the condition of equivalent infinitesimal substitution in addition and subtraction,obtained some conclusions,and finally discussed the special equivalent infinitesimal of 0. |
