| Abstract: | This article tanslates the method of judging and requesting the limit of function of many variables into the method of judging and requesting the limit of one-variable function by spherical coordinates ,then proves it. Accordingly makes it convenient in judging the existence of the limit of function of many variables,and makes it favoring when requestion timit. |
