把Hopf群余代数Ore扩张推广到Hopf群余代数广义Ore扩张,并给出了Hopf群余代数的广义Ore扩张成为Hopf 群余代数的充要条件。%The Ore extension of Hopf group coalgebras is extended to the generalized Ore extension of Hopf group coalgebras .And the necessary and sufficient condition for the generalized Ore extension of Hopf group coalgebras to become Hopf group coalgebras is given .
