摘　　要：杨氏双缝干涉实验中观测的干涉条纹实际上是位于单缝衍射中央明条纹区域内。实际工作中可以将这两个实验综合起来,学生在这个过程中可以清楚单缝衍射与双缝干涉之间的不可分离的关系,有助于学生将理论知识应用于实际,活学活用,促进学生理论水平的提高。This article shows the interference fringe observed in the Young＇s double slit interference experiment is actually located in the single-slit diffraction center of the stripe region.Taken together these two experiments in practical work,students in this process can understand clearly the inseparable relationship between the single-slit diffraction and double slit interference.This helps students to apply theoretical knowledge to practice,learn and use,promoting the improvement of students＇ theoretical level.
