| 摘 要： | 在光的干涉实验中只要测出干涉条纹随金属温度变化的个数,进而求出金属长度随温度的变化量,在光的衍射实验中则利用衍射条纹的间距与缝宽之间的关系,通过测量衍射条纹的间距求出温度变化时待测金属的长度变化量,从而计算出待测金属的线胀系数。

| Abstract: | This paper introduced a method of how to measure the metal linear expansion coefficient using interference and diffraction of light.In light interference,metal linear expansion coefficient can be measured by counting the numbers of interference pattern according to the metal temperature,while in light diffraction,it can be calculated by measuring diffraction stripe space based on the the metal temperature.This experiment can strengthen the students' hands-on ability and inspire their innovative consciousnes... |
