热力学中可逆过程的教学设计

Teaching Design of Reversible Process on Thermodynamics

可逆过程是热力学中最重要的概念之一。通过图表的形式,以1 mol理想气体等温膨胀、压缩过程为例子,通过准静态过程、一次等外压膨胀压缩中功、热以及系统总的热力学能改变的数量直观地讲授了"系统完成一个循环后,系统和环境留都完全复原,没有留下任何影响,这种过程称为可逆过程。否则就是不可逆过程"这一重要概念,完成可逆过程的教学设计。

Reversible process is one of the most important concept.Both systems and surroundings can restore to their initial state and do not leave any influence after a cycle process,which is called reversible process,Otherwise,unreversible process.This important concept can be lecturinged intuitively through charts and tables,by the change of heat,work and the internal energy of a system in a quasi-static process and a constant outside pressure process.A isothermal expansion and isothermal compression of 1 mole perfect gas is exampled.After that,the teaching design is completed.
