热力学中常用的公式多,通过数学变换其形式就更多了读者往往容易混淆而记不清.但是这些公式又很重要,如麦克斯韦关系式就把一些不能直接由实验测定或由态式计算的量与实验上可以测定的量(如C_P)及态式联系起来了.因此熟记热力学中常用公式,对于分析和解决问题是十分重要的.多年来人们根据自己的不同实践创造了许多记忆热力学关系式的方法.本文旨在通过一种“记忆图”的介绍,向读者提出一个问题:热力学函数问的关系是热力学系统的性质的反映,热力学系统的性质是客观存在的,因此每一个热力学函数在诸函数之间必定有自己一定的“地位”,也就是说可能存在一个反映这些热力学函数间关系的“简单图形”.以下就这个问题作一点探讨.
The most commonly used formulas in thermodynamics are those that are more readily transformable by math, and are often confusing and indefinable to readers, but these formulas are important, as Maxwell’s relation puts something that can not be directly determined experimentally or state-by-state Quantity and experimental measurable quantity (such as C_P) and state, so familiar with the thermodynamics commonly used formula for analyzing and solving problems is very important.Over years people according to their own different practices to create a lot of memory thermodynamics The purpose of this paper is to present the reader a question through the introduction of a “memory map”: the relationship between the thermodynamic functions is a reflection of the properties of the thermodynamic system and the properties of the thermodynamic system are objective and therefore each thermodynamic The function must have its own “position” among the functions, which means that there may be a “simple graph” that reflects the relationship between these thermodynamic functions. The following is a brief discussion of this issue.
