| 摘 要： | 针对一般文献中对熵概念理解的混乱的失当之处，对物理学中的熵概念的基本含义进行了疏理．文章讨论了克劳修斯熵和波尔兹曼熵的差别、联系和意义；证明了一般文献对热力学熵公式中作为积分因子的１／Ｔ的Ｔ的解释的失当之处；区别了作为体系结构组构方式变化过程中熵值减少程度和作为体系结构方式偏离标准值的程度的两种不同意义的负熵规定

| Abstract: | In accordance with the muddle in the comprehension of entropy in some literatures, the
basic meaning of entropy in physics is given. The author discusses the meanings of Clausius
entropy and Boltzmann entropy separately, and discusses the difference and relation between
them. The improper explanations of temperature T in some thermodynamic literatures are
pointed. And it is held that a distinction should be made between the negative entropy for
measuring the entropy change in the varying process of the construction manner of system
structure and the negative entropy for measuring the degree of the construction manner of system
structure off the normalized value. |
