The mean entropy per character may be expressed in a unit such as a Shannon per character.2.The limit of Hm/m may not exist if the source is not stationary. 对来自一平稳信息源的所有可能信息的每字符熵的平均值,用数学表示为: 如Hm是来自一信息源所有m个字符序列组的熵,则每字符的平均熵为H′=limm→∞ Hmm。注:1. 每字符平均熵可用一个单位(如每字符香农)来表示。 2. 如信息源不平稳,则Hm/m的极限可能不存在。同mean information content (per character), average information content (per character),information rate (per character)。
