中文摘要：

在自然界中，许多过程都是非平衡态过程。要研究这些过程，仅靠经典热力学是远远不够的。本文介绍了非平衡态热力学的主要理论，综述了非平衡态热力学的研究进展，介绍了非平衡态热力学在各个领域中的应用现状，指出随着非平衡态热力学理论的发展，它将在越来越多的领域得到广泛的应用。

英文摘要：

In nature, many processes are non-equilibrium. It＇s not enough to find a solution to research these processes only relying to classical thermodynamics. In the paper, importent theory of non- equilibrium thermodynamics is introduced briefly. Its application in kinds of domain is summarized. Non-equilibrium thermodynamics will be used in more and more field along with it＇s development.
