摘要：

This paper proposes the new transformation, namely the contractive homothetic transformation. proving that the smooth degree of the series will be improved by using this transformation. Not only the difference information will be decreased, but also the error of class ration will be reduced. At the same time, the smooth degree of the class approaches will be greatly advanced after being processed by this transformation, whether the series is monotone descending, or monotone ascending.
