【摘要】 本文针对目前国内高等学校“无机化学”和“普通化学”教材中化学热力学函数变量的量纲不统一的问题,从“物质的量”的单位“摩尔”的概念及使用“摩尔”时必须指明基本单元出发,说明这些变量的量纲应含mol^-1,对其意义作了讨论,在有关计算公式中等式两边量纲不等的问题也加以澄清,说明各变量的量纲中含mol^-1意义明确,符合使用摩尔必须指明基本单元的规定,也不会给计算带来量纲不等的矛盾。更多还原

【Abstract】 Aiming at the inconsistency of quantitative units in variables of chemical thermodynamic functions in China’s present day university textbooks of chemistry and inorganic chemistry, this paper sets forth the idea that the quantitative units of these variables should include mol^1 and discusses its significance from the concept of the unit of "the amount of substance"----"mole" ,and the need to point out the elementary entity when using "mole" . It also clarifies the problem of unequality on the two sides of the equation in certain formulae concerned, saying that mol""1 is justifiably included in the qualitative units of the variables, which is in line with the rule that the elementary entity must be pointed out when using mole and which will not bring abont the problem of inconsistency of quantitative units in calculation.更多还原
