摘　　要：利用单缝衍射条纹的间距与缝宽的关系,通过测量条纹间距,得到狭缝的宽度,而缝的宽度随固体材料的膨胀而发生变化,由此可测量出固体的膨胀系数.Based on the relation between stripe space and slit width, which varies with the expansion of metal slit, in single slit diffraction, the expansion coefficient of metal is determined by measuring the stripe space.

关 键 词：膨胀系数 单缝衍射 氦氖激光器
