摘要
利用光的衍射和干涉原理，从单缝衍射和双光束干涉出发，分析狭缝宽度不同时双缝夫琅禾费衍射光强的分布规律，并讨论一狭缝宽度是另一狭缝的两倍时，双缝衍射出现暗纹的条件和明暗纹的排列，再进行模拟计算，得出几种特殊条件下双缝衍射光强的分布曲线．
From the single＇slot diffraction and double-beam interference, using the principle of fight diffraction and interference, the distribution law of double-slot Fraunhofer diffraction light intensity of different slot width is analyzed, the condition needed for the shade streak to appear and the array law of light-shade streak are discussed when one slot width is twice of the another. Several special distribution curves of double-slot diff action light intensity are obtained after the simulating computation.
