(一) 自从”关於相规的推导法的一点补充意见”一文在本年化学通报1月号发表后,我们非常高兴地读到了华保定同志所提的,关於“体系中任一组分在体系的各相中是否都存在”这一问题的讨论意见。华同志的意见实际上接触到一个更为重要的问题,即是否足够注意“热力学理论的宏观性质”的问题。因此,先把这一问题提出来谈一谈,我想一定会有许多同志感觉兴趣的。我们知道相规是热力学的一部分,而热力学是一种宏观理论。在热力学中所用的描写物态的变数和函数都是宏观量。从分子运动论看来,也就是从微观方面看来,这些宏观量都是平均数,都是统计
(1) Since the publication of the “Supplementary Opinion on the Derivation Law of the Conformity,” published in the January 1 Chemical Bulletin of the current year, we are very pleased to read Comrade Hua Baoding’s remark that “any component of the system is Whether the system exists in all phases ”of the discussion of this issue. Comrade Hua comrades in fact touched upon a more important issue, namely, whether he paid sufficient attention to the issue of “the macroscopic nature of thermodynamic theory.” Therefore, let me talk about this issue first and I think many of you will surely feel interested. We know that phase theory is a part of thermodynamics, which is a macro theory. The variables and functions used to describe states of matter in thermodynamics are macroscopic quantities. From the perspective of molecular motion theory, that is, from the microscopic point of view, these macroeconomic quantities are the average, are statistics
