摘要：“汽”和“气”是化工热力学的两个基本概念,但大部分学生不能厘清二者的区别。为此,我们在化工热力学教学中,首先利用临界温度帮助学生理解“汽”和“气”的关键区别;其次通过“汽液平衡”和“气液平衡”、“蒸汽动力循环”和“燃气动力循环”进一步讨论了“汽”和“气”的不同用法。
Vapor and gas are two basic concepts in chemical engineering thermodynamics,but most college students cannot distinguish them well.Hence during the teaching activity,the critical temperatures of vapor and gas are taken as a starting point to help students to understand the key difference in-between.Further,the differences in the applications of vapor and gas are illustrated systematically through the knowledge points on vapor-liquid equilibrium and gas-liquid equilibrium,vapor power cycle and gas power cycle.
