信息熵与统计力学熵相同吗?

Is the Information Entropy the Same as the Statistical Mechanical Entropy?

Phil Attard

摘要:

它示出的信息熵的标准表达式,最初由于香农,是只适用于一组特定的状态。对于统计力学的一般情况,需要在作为概率函数的熵的表达式中包括一个附加项。并给出了一般公式的一个简单推导。

英文摘要:

It is shown that the standard expression for the information entropy, originally due to Shannon, is only valid for a particular set of states. For the general case of statistical mechanics, one needs to include an additional term in the expression for the entropy as a function of the probability. A simple derivation of the general formula is given.
