摘要

研究了用修正Enskog方程描述的稠密气体与热浴接触的封闭系统的热弛豫。与玻尔兹曼方程一样，在满足Darrozes—Guiraud不等式的常规动力学边界条件下，发现亥姆霍兹自由能$\mathcal{F}$随时间单调减小。给出了修正的Enskog—Vlasov方程的推广。

On the thermal relaxation of a dense gas described by the modified Enskog equation in a closed system in contact with a heat bath

The thermal relaxation of a dense gas described by the modified Enskog equation is studied for a closed system in contact with a heat bath. As in the case of the Boltzmann equation, the Helmholtz free energy $\mathcal{F}$ that decreases monotonically in time is found under the conventional kinetic boundary condition that satisfies the Darrozes--Guiraud inequality. The extension to the modified Enskog--Vlasov equation is also presented.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
