摘　　要：作为强Hopf(Co-Hopf)模的真推广,引入小强Hopf模和本质强Co-Hopf模并研究这些模的性质.举例说明小强Hopf模不一定是强Hopf模且本质强Co-Hopf模不一定是强Co-Hopf模.As proper generalization of strong Hopf（Co-Hopf） modules, small strong Hopf modules and essentially strong Co-Hopf modules were introduced and their properties were studied. Examples showed that a small strong Hopf module need not be a strong Hopf module and an essentially strong Co-Hopf mod- ule need not he a strong Co-Hopf module.

关 键 词：强Hopf(Co-Hopf)模 小(本质)强Hopf(Co-Hopf)模 离散模 拟离散模 连续模 拟连续模
