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 po-tentials of manysubstances． 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 onitself． Through a detailed a-nalysis，it is demonstrated the chemical potential in general depends on all substances within thesystem．
