Coleman-Noll关系式与熵函数存在条件

Coleman-Noll Conditions and Existence of Entropy

本文以Coleman-Noll关系式(特指使Clausius-Duhem不等式成立的充要条件)为基础,对内变量理论、粘弹性及塑性流动理论等情形研究了熵函数存在条件的具体形式以及熵函数应具有的表达式等相关问题.

In this note, on the basis of the Coleman-Noll conditions, we discuss the following three problems:1. the expression of entropy defined by Coleman-Noll conditions;2. the sufficient and necessary conditions of existence of entropy;3. the uniqueness of entropy.
