从力学到热力学--例题分析
From mechanics to thermodynamics -- analysis of selected examples
摘要:
我们提出并讨论了一组选定的问题的经典力学和热力学。讨论的基础上使用的冲量动量方程同时与质心(伪功)方程或热力学热力学第一定律,这取决于问题的性质。在不同的参考系中,结合一个或另一个能量方程的使用以及相对性原理的遵守,讨论了经典力学的热力学方面,即涉及非保守力或机械能变化的问题。
英文摘要:
We present and discuss a selected set of problems of classical mechanics and thermodynamics. The discussion is based on the use of the impulse-momentum equation simultaneously with the centre-of-mass (pseudo-work) equation or with the first law of thermodynamics, depending on the nature of the problem. Thermodynamical aspects of classical mechanics, namely problems involving non-conservative forces or variation of mechanical energy are discussed, in different reference frames, in connection with the use of one or the other energy equation, and with the compliance of the Principle of Relativity.
