摘要
材料科学基础课程的知识理论丰富,体系分支较多,概念理论较为分散,一些原理比较抽象难懂,课本中存在若干易引起歧义论述。文章以液固系统自由能变化与形核关系及位向和取向区别为例,以图例方式进行了阐述和辨析,帮助学生深入理解抽象理论及概念,这可为材料科学基础的教学提供新的思路,有利于提高本门课程的教学效果。
The material science foundation course has rich knowledge theory, many system branches, and the concept theory is scattered. Some principles are more abstract and difficult to understand. There are some ambiguous arguments in the textbook. Taking the relationship between free energy change and nucleation of liquid-solid system and the difference of position and orientationrelationship as an example, this paper elaborates and differentiates with illustrations to help students deeply understand abstract theories and concepts, which can provide new ideas for the teaching of material science foundation and is conducive to improving the teaching effect of this course.
