| Abstract: | In the paper,the author first points out the deficiency in introducing the method of successive minus to the current textbooks,expounds the necessity of rediscussing dealing with data by means of successive minus.Then on the basis of analysis of the application of the method of successive minus to experiment of measuring Yang's Mudulation by drawing steel wire,the author puts forward his opinion on the article of It Is Not Scientific to Deal with Data by the Method of Successive Minus. |

| Keywords: | method of successive minus difference between each two adjacent terms difference between the corresponding terms of two groups dealing with datas |
