摘要
本文从一个实验事实出发，说明在实际的夫琅禾费衍射实验装置的观察屏上所显示的条纹，是理想的夫琅禾费衍射的一种近似，仅在一个较小的范围内，衍射条纹才比较严格地符合夫琅禾费衍射规律。
Abstract Starting from experiment it is shown that the diffraction pattern is anapproximae pattenn of the ideal Fraunhofer diffraction on the Screen of the Fraunhoferdiffraction. Two diffraction patterns agree at only a relatively small region.Kev words Fraunhofer diffraction；inclination factor；observation range
