本文将固体物理的教学内容与凝聚态物理的研究前沿紧密联系，以金属化合物材料二硼化镁为教学案例，使用较为直观的语言，深入浅出地介绍了固体物理中晶格结构、能带理论、态密度和声子色散关系等基础知识. 将学科前沿进展转化为教学案例，融入到固体物理教学中，不但能丰富教学内容，让课堂生动有趣，还能帮助学生理解抽象的物理概念，建立清晰的物理图像，达到良好的教学效果. 

In this paper, taking the research frontier of condensed matter physics into the teaching content of solid state physics is focused. Metal compound material magnesium diboride is taken as a typical case to guide students to deeply understand the lattice structure, energy band structure, electron state density, phonon dispersion relationship and other basic knowledge. It has been proved that the introduction of the technological frontier in teaching could not only make the teaching content more vivid and interesting, but also help students to understand abstract physical concepts, establish clear physical images, and improve the teaching effect of solid state physics.
