摘　　要：二元流体临界体系相平衡的研究是临界流体科学与技术发展的重要组成部分,临界流体技术作为一种新型高效绿色化工技术,在许多重要工业领域显示出了巨大的应用前景.从二元流体临界相平衡的理论进展、实验进展和模拟进展等方面进行了概述总结,发现近临界点的热力学数据不够完善,应该进一步研究二元流体临界相平衡远离平衡态的耗散理论的普适性.Binary fluid critical phase equilibrium system is an important part for the development of science and technology of supercritical fluid.The supercritical fluid technology,which is a new type of high efficient green chemical technology in many important industrial fields,shows a great application prospect.This paper summarizes the theory progress,experimental progress and simulation progress for the binary fluid critical phase equilibrium.We find that the imperfection of the thermodynamic data closing to the critical point.Binary fluid critical phase equilibrium should pay more attention to the research of universality of the critical phenomenon of dissipation theory away from the equilibrium state.The universality of dissipation theory of the binary fluid critical phase equilibrium away from the equilibrium state should be further studied.
