用L′HOSPITAL法则判定二元函数极限的不存在

A Decision Method About Non--existence of Limit of a Binary Function by L′Hospital’s Rule

本文介绍了一种利用Ｌ＇ＨＯＳＰＩＴＡＬ法则判定二元函数极限不存在的方法，并对其适用范围进行了讨论。

In this paper,a new decision method about non-exsitence of limit of a binarg function by L’Hospital’s rule is introduced,and on the basis of it,the applicable range of the decision method is discussed.
