revent meaning in Chinese

雷文特

The paper do n ' t attempt to definite new generalized metric space classes and new covers and mappings . this is because in the development of revent several decades in topology , the space classes were definited by all sorts of formal generalizations have reached a flooded extent , continual introduction of new spaces and over tiny division have made topology develop to an empty theorical margin
本文不试图去定义新的广义度量空间类以及新的覆盖与映射，这是因为近几十年拓扑学的发展，各种形式的“推广”所定义的空间类已达到泛滥的程度，新空间的不断引入，过细的划分使得拓扑学似乎发展到了空洞的理论边缘。
