摘要
该文主要是讨论了Ｈｏｐｆ代数同态的左（右）Ｈｏｐｆ核的一些性质，而且还引入了Ｈｏｐｆ代数同态序列的定义．与此同时又给出了一个有限维Ｈｏｐｆ代数的Ｈｏｐｆ同态序列正合的充要条件。
The aim of the paper is stuty the properties of left(right) Hopf kernel of Hopf algebra homomorphisms, The sequence of Hopf algebra homomorphisme is introduced, and so is a necessary and sufficlent condition for the Hopf homomorphism sequence to be exacted with finite dimensional Hopf algebras.
