《物理化学》中化学势符号的系统规定

Systematic Convention of Chemical Potential Symbols in Physical Chemistry

现行物理化学教材中的化学势符号形式上不够统一,学生在学习各种体系的化学势表达式这一部分时感觉非常困惑和困难。本文通过比较分析国内广泛使用的两本教材中的化学势符号,归纳提出了一套关于化学势符号的系统规定。按照这套符号规定,每一个化学势都有唯一确定的形式,而且与体系有直观明确的对应关系,让人一看符号便能认出是什么体系的化学势或是什么样的标准态,有助于学生对这部分内容更好的理解和掌握。

The chemical potential symbols are not uniform in physical chemistry textbooks. Thus students often feel difficult and confused when they learn the mathematical expressions for chemical potential of various systems. A new systematic convention of chemical potential symbols was proposed after a comparative study of two widely used textbooks.According to this convention,every chemical potential had a definite form corresponding to a certain system,will help the students to understand chemical potential and the mathematical expressions.
