基于已有文献对Raabe判别法的一、二步改进,类似地将其推广到了三步以及更一般的多步改进的情形,实例表明此类改进是有实效的。

To generalize the Raabe criterion so that the convergence of the positive series mentioned in this paper can be tested ,Wang and Liu give a one-step and two-step improvements .We use the similar method to get a three-step improvement and more .The generalization is found more effective than before by some examples .
