熵和弛豫时间

Entropy and relaxation time

Jeppe C. Dyre

摘要:

本文讨论了熵与液体(特别是玻璃形成系统)的弛豫时间之间的可能关系,为Hecksher等人的题为“A brief critique of the Adam-Gibbs entropy model”的论文[J. Non-Cryst. Solids 325,624-627(2009)]提供补充评论。除了Adam-Gibbs模型,我们还简要讨论了Rosenfeld的过剩熵标度和1964年Chang和Bestul对玻璃化转变时普遍过剩熵的实验观察。

英文摘要:

This paper discusses the possible relation between entropy and the relaxation time of liquids, in particular glass-forming systems, providing supplementing comments to the paper entitled "A brief critique of the Adam-Gibbs entropy model" by Hecksher et al. [J. Non-Cryst. Solids 325, 624-627 (2009)]. Besides the Adam-Gibbs model, we also briefly discuss Rosenfeld's excess entropy scaling and the 1964 experimental observation by Chang and Bestul of a universal excess entropy at the glass transition.
