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.
對多元函數的重極限進行深入探討,得到變量趨于一點時重極限存在的充要條件,併把結論推廣到變量趨于無窮的情況.

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.
