| Abstract: | Using elementary methods,the positive series judge method In-depth is studied,Based on the idea of Ratio test and the root value based identification method,this paper gives a new and more exact criterion.Furthermore,it proposes a general idea to construct a series of criterions with increasing precision.By the way,it proves that there is no best criterion that can judge every series by comparing the quotient of adjacent terms,or there is no positive term series that have the lowest speed of convergence. |

| Keywords: | positive term series judge method speed of convergence |
