热学研究的内容是热现象及其规律。它是以两方面展开的,一是从微观角度,用分子动理论的观点揭示热现象的本质;二是从宏观角度,以观测和实验事实为依据,寻求热学参量之间的关系,用能量的观点认识热现象。要复习好热学知识,首先应把微观角度的分子动理论和宏观角度的实验和事实掌握好,弄清热学中的微观量和宏观量的联系。其次要把反映热学参量关系的规律理解透。最后能够把热学知识与日常生产、生活实际联系起来,解决实际问题。
The contents of thermal studies are thermal phenomena and their laws. It is developed in two aspects. First, from the microscopic point of view, the theory of molecular dynamics is used to reveal the nature of thermal phenomena. Second, from the macroscopic point of view, observations and experimental facts are used as the basis for the search for the relationship between thermal parameters and the use of energy. The point of view recognizes the phenomenon of heat. To review the knowledge of thermodynamics, we must first grasp the microscopic perspective of molecular dynamics theory and the macroscopic perspective of experiments and facts, and clarify the connection between microscopic and macroscopic quantities in thermal science. Second, we must understand the laws that reflect the relationship between thermal parameters. Finally, we can connect thermal knowledge with daily production and real life to solve practical problems.
