液体精馏是化工原理课程中的重要组成部分,而精馏原理则是解决液体精馏部分所有问题的基础,同时也是学生学习中的难点所在。结合教师在实践教学中的经验,将精馏原理切割为理论精馏过程和实际精馏过程两个教学环节,利用多媒体资源,构筑知识脉络,取得了良好的教学效果。 Liquid distillation is an important part of the course of chemical theory, and the principle of distillation is to solve all the problems of liquid distillation part of the basis, but also the difficulties of students learning. Combining with the experience of teachers in practice teaching, the principle of distillation is cut into two teaching links: theoretical distillation process and actual distillation process. Multimedia resources are used to build knowledge and good teaching results are achieved.
