摘　　要：对多元函数的重极限进行深入探讨,得到变量趋于一点时重极限存在的充要条件,并把结论推广到变量趋于无穷的情况.A necessary and sufficient condition of double limit existentially was given based on the analysis of limit of many variable when variables trend to a point, and the conclution was generalized to variables trend to infinity.

关 键 词：重极限 充要条件 一致性
