摘要
本文讨论了无线口径衍射场分布的相似性问题．对一定的口径分布，当口径特征尺寸、波长及观察平面至口面的距离改变时，衍射场分布存在两种不同的相似性．即电尺寸恒定时的＂严格相似性＂及电尺寸变化时的＂渐近相似性＂．
In this paper, the similitude problem in aperture was examined. With the changes of aperture characteristic size, wavelength and the distance from observation plate to aperture,there are two different similarities in the diffraction field distribution for a specified aperture distribution, the strict similarity when electronical size is constant and the asymptotic similarity when it changes.
