关于熵的一个引理的证明

The Proof of a Lemma about Entropy

介绍了信息论中熵的概念,给出了熵的一个引理,并对该引理给出了详细的证明,进而说明了熵的连续性。

In this paper,the concept of entropy in Information theory is stated,and a lemma in the book of Information theory： coding theorems for discrete memoryless systems is given.The lemma is proved correctly and in detail.Then the continuity of the entropy is illustrated.
