高中一册物理《教参》３９页介绍了一种坚硬物体微小弹性形变的演示方法，此方法对光源要求高，各部件之间相对位置的调整较难，实验前准备时间长。这里介绍一种简便的演示方法，以供同仁商讨。ａ．制作：①取两个高铁架台，放在同一水平面上；②取同宽米尺两根，分别用两... A physics textbook “Guangshu” on page 39 describes a demonstration method for the small elastic deformation of a hard object. This method requires a high light source, makes it difficult to adjust the relative position of each component, and takes a long time to prepare before the experiment. Here is a simple demonstration method for colleagues to discuss. a. Production: 1 take two high-speed rail stand, placed on the same level; 2 take two meters with the same width, respectively, with two ...
