摘　　要：对于内壁光滑的圆柱状金属管,从开口处观察可以发现亮度不连续分布的光环.本文利用平面镜实验初步验证了产生该现象的基本原理.通过建立模型,运用MATLAB进行模拟,对该现象产生的基本原理进行解释.最后采用实验与模拟结合的方式对影响光环的系列因素进行探究.Looking into a cylindrical metal tube with smooth inner walls,bands with discontinuous distribution of brightness can be found.The basic principle of this phenomenon is preliminarily verified by mirrors.In this paper,the basic principle of the phenomenon is explained by establishing the model and using MATLAB to simulate.Finally,the combination of experiment and simulation is used to explore the series of factors which affect the phenomenon.
