在高中新教材(试验用)第一册第一章中,新增加了一个显示微小形变的演示实验,书中介绍的实验方法是让一束光通过一组平面镜的两次反射,来放大桌面受压所产生的形变,但对所用仪器并未作具体说明,实验效果也不明显。因此,我们设计了一个演示微小形变的装置。1实验装置这套
In the first chapter of the first volume of the new textbook for senior high school students (experimental), a new demonstration experiment showing a small deformation was added. The experimental method introduced in the book is to enlarge the tabletop by letting a beam of light reflect twice through a set of plane mirrors. Deformation caused by compression, but no specific description of the instrument used, the experimental results are not obvious. Therefore, we designed a device that demonstrates tiny deformations. 1 experimental device this set
