摘　　要：本文研究了环上模范畴与余环上余模范畴. 运用可裂叉与余可分余环的性质, 得到了以上两个范畴等价的一些充分条件, 从而推广了文献[6]中的一些结果.In this article, we consider the categories of modules over rings and categories of comodules over corings. By properties of split forks and coseparable corings, we get some sufficient conditions for the equivalence between above two categories. As a consequence, we generalize some results in [6].
