中文摘要：
偏摩尔量是化工热力学中一个重要的热力学概念,总结了偏摩尔量的概念、定义和包含范围,并叙述其物理意义和性质。发现二元组分溶液中利用摩尔量计算偏摩尔量公式的证明过程复杂,部分结论较为隐晦,不容易理解。利用摩尔量之间的关系、摩尔组成之间的关系以及摩尔组成的定义得到三个的微分等式,并利用这三个微分等式通过简便的证明过程即可得到利用摩尔量计算偏摩尔量的证明。简便证明简单可靠,容易理解,且相应的简便证明过程可以推广至多元溶液的一般过程。在证明过程中,如果不利用相关隐含公式和结论,则相关证明结论无法得到。在实际利用摩尔量计算偏摩尔量的过程中,通过对比可知,利用相关定义和隐含微分公式,可以大大简化计算过程和步骤。

英文摘要：
As an important thermodynamic concept in chemical thermodynamics,the concept,definition and scope of partial molar quantity are summarized,and also its physical significance and properties are described.It is found that the process of proving the partial molar formula in the binary solution in the textbook is complex,and some conclusions are obscure and not easy to be understood.Three differential equations are obtained from the relationship between the molar quantities,the relationship between the molar compositions and the definition of the molar compositions.The promoted proof is simple,reliable and easy to be understood,and the proving process can be extended to the general process of multicomponent solution.The relevant proof conclusion can not be obtained if we do not use the relevant implicit formula and conclusion.By comparison,it is known that the calculation process and steps can be greatly simplified by using relevant definitions and implicit differential formulas in the actual calculating process of partial molar quantity by using molar quantity.
