摘要:溶液临界现象是热力学研究中的一个重要领域,其对于认识临界普适性规律以及理解和应用由于超常临界涨落引起的溶液特殊性质具有重要意义.本文简述了临界现象的基本概念和研究历史,介绍了近年来溶液临界现象的研究进展,重点评述了以下几个方面的理论和实验成果:(1)临界指数与指前因子标度关系在溶液体系中的普适性;(2)完全标度理论的建立、发展及其实验检验;(3)临界区域与非临界区域的跨接现象;(4)多元溶液中的三临界现象;(5)临界溶液中的化学反应速率及平衡常数的奇异性.
The critical phenomenon is an important research field in thermodynamics, which is important not only to understand the critical universality but also to understand and apply the singularity of solutions driven by the anomalous critical fluctuation. In this review, we sketched some basic concepts and the research history in this field, overviewed the recent progress on the critical phenomena of solutions with emphasis on (1) the universality of the critical exponents and the scaling ratios of the critical amplitudes in solutions; (2) the development and verification of the complete scaling theory; (3) the crossover phenomena between the critical region and the classical region; (4) the tricritical phenomenon in multicomponent systems; (5) the anomalies of the reaction rate and the equilibrium constant for the chemical reactions in the critical solutions.
