摘要
相平衡是化工热力学课程的核心内容,也是传质分离的理论基础。由于相平衡涉及到许多抽象的概念和复杂的数学公式,使得学生难以掌握,教学效果较差。本文采用框图的形式,针对中、低压下非理想汽液平衡体系,分别介绍了泡点p、露点p、泡点T、露点T的计算过程,该方法能够通俗易懂将计算过程中所用到的概念和公式传达给学生,让学生在后续课程中能够独自应用,提高了教学和学习效果。
Phase equilibrium is not only the core content in the Chemical Engineering Thermodynamics,but also the theoretical basis of mass transfer separation.However,it is difficult to grasp for students because phase equilibrium has many abstract concepts and complex formulas,which will result in poor effects.For non-ideal vapor-liquid equilibrium at low-medium pressure,the teaching methods combining the easily understood charts on calculating of BUBL p,DEW p,BUBL T and DEW T were adopted,which can effectively communicate those abstract concepts and complex formulas to students and enable students to apply independently in subsequent courses.Teaching and learning effects were improved a lot.
