Let L and A be Hopf algebras on field k with antipodes s_L and s_A, B being a right A-comodule algebra, C a right A-module coalgebra. The defination of (A, B)-Hopf module and the fundamental structure theorem on (A, B)-Hopf module in L_LYD were given.

- 設L是域k上的Hopf代數;其對極為sL; A是-Hopf代數;其對極為sA;B是右A余模代數;C是右A模余代數;給出LLYD中(A;B)Hopf模的定義以及LLYD中(A;B)-Hopf模的基本結構定理;并討論了其對偶情況.
