摘　　要：通过理论分析得出双缝实验中空间光场的分布是干涉与衍射共同作用的结果.在形成条件、分布规律以及数学处理方法上说明了干涉和衍射的区别与联系.It is derived through theoretical analysis that the spatial distribution of light field is resulted by both interference and diffraction in the double-slit experiment. Both the connection and difference between interference and diffraction are introduced based on forming condition and distribution regularity and mathematical treatment method.

关 键 词：双光干涉 单缝衍射 光强分布
