摘　　要：在热力学中,关于多元系的化学势的变量集,有互不一致的两种结论.一种结论认为,某种物质的化学势,仅仅依赖于其它物质的存在,另外一种认为,不仅依赖于其它物质,也依赖于自己.本文通过详细的分析论证了,一般而言,化学势依赖于系统内的所有物质.In thermodynamics,there are two different assertations about the set of variables for the chemical potentials of many substances.One is that the chemical potential of a certain substance only depends on the existence of other substances;and another is that it depends not only on other substances,but also on itself.Through a detailed analysis,it is demonstrated the chemical potential in general depends on all substances within the system.

关 键 词：热力学 化学势 特性函数 强度量 广延量
