在人教版普通高中物理课程标准实验教科书必修1第3章“弹力”一节中附录了一张绚丽多彩的“有机玻璃的形变”图片,教材指出:“在图3.2-2中,一块三角形有机玻璃压在另一块有机玻璃上,发生的形变很小,肉眼不能看出,但是,形变使有机玻璃内不同部位的光学性质产生了差异,让特殊的光通过时,可以看到这种差异.”其实这样一张令人感到惊艳的图片完全可以在课堂教学中呈现出来,让每个学生都能通过亲身观察来深刻体验这种物理学 In the People’s Education Edition of ordinary high school physics curriculum standard textbook compulsory 1 Chapter 3 “elastic ” section attached a colorful “plexiglass deformation” picture, the textbook states: “in Figure 3.2- 2, a triangular plexiglass pressure on another piece of plexiglass, the occurrence of deformation is small, the naked eye can not see, but the deformation of the plexiglass optical properties of different parts of the differences, so that special light through, you can See this difference. ”" In fact, such a stunning picture can be fully demonstrated in the classroom teaching, so that each student can personally experience through this profound experience of this physics
