It was illuminated that the width of the centre bright fringe decreased along with the increasing width of the rectangular aperture when the effect of the aperture on the beam couldn't be ignored,however,the width of centre bright fringe step changed with increase of the size of the aperture when the effect could be ignorable,the width of the half maximum intensity of the centre bright fringe decreased along with the accretion of the width of the aperture and then it tends to a constant.

结果表明，当光阑对光束的衍射影响明显时，光束衍射场的中央亮条纹的宽度随着光阑边长的增大而减小；当光阑对光束的衍射影响极小时，中央亮条纹的宽度随着光阑边长的增加而阶跃变化，中央亮条纹强度的半最大值宽度随着光阑边长的增大而减小；当光阑对光束衍射影响极小时，中央亮条纹半最大值宽度趋近于一定值。

aperture：口径

望远镜的能力便完全依赖于这些透镜的直径,这便叫做望远镜的"口径"(aperture). 口径的大小不等,可以从家用小望远镜的10厘米左右,一直到叶凯士天文台(YerkesObservatory)大型折射望远镜的1.02米. 三百年前的天文学家都以为绝无办法避免透镜的色散作用.
