准静态过程及相关物理概念教学探析

Analysis on Teaching of Quasi-static Process and Related Physics Concepts

本文运用类比方法，引入爬台阶这一常见生活实例，通过对其作细致的定性和定量分析，直观形象地类比了热力学中的准静态过程及相关物理概念，揭示了平衡态、非平衡态、弛豫时问等概念之间以及他们跟准静态过程的内在联系和本质区别，进一步明确了将实际过程近似为准静态过程的定量条件．

In this paper we adopt the analogy method and introduce the process of climbing steps as an example.We give an intuitive analogy of the quasi-static process and related physical concepts in thermodynamics through a detailed qualitative and quantitative analysis on the process of climbing steps.We reveal the difference between the conceptions of equilibrium state,non-equilibrium state,and relaxation time,and show the connection of them to the concept of quasi-static process.We give the quantitative condition for practical process approximating to quasi-static process as well.
