显微演示系统在金相实验教学中的应用

Application of a Micro-demonstration System to the Teaching of Metallographic Experiment

针对工程材料金相实验中存在的问题，如学生不仅缺乏实践经验，而且对实验课不够重视等因素，严重影响教学效果和实验质量。采用显微演示系统，改进实验教学的方法和手段，提高了实验的效率和质量。

Students lacking experience and looking down on the Metallography experiment are partly responsible for the existing problems in experimental courses, which undermine the experimental teaching quality seriously. Adoption of a micro-demonstration system not ouly improves the means of teaching experiments but also raises the experimental efficiency and quality.
