随着科学技术的发展，各行业对物理化学性质的需求越来越多，越来越高。基于物理模型的“第一原理”虽然近年来获得了长足的进展，但是它离提供实际数据的要求尚有一段很长的距离。“经验模型”仍然是获取物理化学数据的主要方法。一个多世纪以来化学工作者，材料工作者，以及其他各行各业的科学工作者，都为改进这种模型的计算做出种种努力。但是，人们突然发现，其实他们都是从不同的角度做着同样的事情。这些模型仍停留在半个世纪以前的水平。究其原因，主要是把“经验模型”往理论高度提升中遇到了困难，无法从理论上跨越通往“自洽”的门槛。它已严重地影响到当前对各种物理化学数据的计算，尤其是对高阶体系的计算。本课题拟将我们以往提升“经验模型”的方法，运用到高阶体系中，实现把“经验模 型”全面发展为“唯象理论模型”的目标。本工作的完成，其影响将不止是冶金和材料行业， 对国民经济的其他部门，如能源、化工等都会产生有益影响

With the progress of science and technology, there are more and more needs for the physicochemical data. Though the “first principle calculation” has made a great step recently, it is still a long way to offer practical data. The “empirical method ”is still the main approach to obtain these kinds of data. In the past century, many metallurgists and metallists as well as the scientists from other fields have devoted their efforts to improve this kind of model; nevertheless, no progresses have been made. The calculation models still stayed in the same level of half century ago and cannot see any indication for future development. All of these have seriously affected to offer physicochemical data, especially for some higher order multicomponent systems. In this project, our goal aims to develop a kind of “phenomenological model” for the higher order systems starting from the current “empirical model” based on our suggested principle that has already been demonstrated as a successful approach to deal with ternary models before. It is expected that the benefit of this new development will not be limited in the metallurgy and material science only but will extend to different fields, such as, agriculture, chemicals, energy, medicine and health…and so forth
