| 摘 要： | 总结了当前国内外关于流体的热力学前缘研究领域如下：（１）流体体系的ｐ－Ｖ－Ｔ－ｘ相关系研究，主要对象是Ｈ２Ｏ－ＣＯ２－盐类多组分体系高温高压下相图的实验和理论研究。（２）矿物在流体中的溶解度及溶解后在流体中溶解类型的形式和热力学性质——平衡常数（或Ｇｉｂｂｓ自由能）及各种偏摩尔性质的研究。（３）流体热力学模型化研究，已研制出大量的计算机软件，包括多种矿物、溶解类型的热力学数据库和模拟热液平衡、矿物溶解性质、反应路径和水—岩相互作用的实用程序。（４）超临界流体的相关系和化学反应等有许多特殊的性质，对认识地球内部的演化将有重要意义。（５）新技术新方法的发展，使分析单个矿物包裹体成分变成了现实。

| Abstract: | The frontier aspects of thermodynamics of fluids have been summarized as follows: (1) experimental and theoretical study on p V T x phase relationship of multicomponent systems such as H 2O CO 2 salt at high pressures and high temperatures, (2) study on solubility of minerals and species in fluids and their thermodynamic properties equilibrium constant and standard molal properties, (3) thermodynamic modelling of fluids, a number of software have been developed including the data base of thermodynamic properties of minerals and aqueous species in fluid and practical programs for simulating fluid equilibrium, mineral solubility, path of reaction and interaction of water rock, (4) a number of specialities of chemical reaction and phase relationship in supercritical fluid are very important for understanding the evolution of the Earth, (5) the development of new analytical techniques and methods makes it possible to analyze the composition of individual inclusions. |
