If one of the following conditions is satisfied , then the trivial extension T of H is not a bialgebra .(1) H is not a Hopf algebra ,(2) H is a Hopf algebra , but the antipode of H is not the identity map .(3) char can not divide 2dim H .

若下述三个条件之一成立，则T不是双代数：(1) H不是Hopf代数，(2) H是Hopf代数，但其反极元S不是恒等映射，(3) char不能整除2dim H。

To cousider the least,we have to establish these facts under some comparablystrong but not the most proper conditions.From [12] and [13],if we suppose thatfis Lipschitz continuous in t,then all the above conditions(H1)-(H3) canbe established to a class of approximating problems of (1)(2).So the followingtheorem can be proved by theorem 5 through approximation process.

这时，我们只好"退而求其次"，在较强的"看来不是最适当的条件"下，来建立这些事实，从[12]和[13]中我们看到，只要加上"〓对t为Lipschitz连续"，则对（1）（2）的逼近问题族，上述条件（H1）-（H3）都可建立起来，从而，通过逼近过程，用定理5就可得到如下的定理。

The finder is a navigator rather than archeologist, their nature can't explain these problems and I think that the archeologist in that time isn't also hermeneutic.
