综述了近年来国内外学者对超临界气体在固体表面吸附的研究情况。指出了气体在临界温度以上吸附与临界温度以下吸附的不同之处 ;对现行的关于超临界气体的吸附理论研究进行了讨论 ,并在此基础上提出了研究中存在的问题及进一步的研究方向。 In this paper, the domestic and foreign scholars on the adsorption of supercritical gas on solid surface in recent years are reviewed. The difference between the adsorption of gases above the critical temperature and the adsorption below the critical temperature is pointed out. The current theoretical study on the adsorption of supercritical gases is discussed, and the existing problems and further research directions are put forward .
