摘　　要：随着膜技术的发展,在汽车贴膜上的应用也越来越多,在生活中发现的奇特现象也越来越多[1],在本文中,根据发现“透过车窗玻璃膜观察路灯时会出现一条超长的亮线”这一现象,进行机理上的初步探究。本文先进行初步分析:运用光学知识分析以及Matlab仿真分析推断可能的结构与机理———在光源到人眼这一光路中一定存在某一超细的细缝(丝)或光栅结构,接着实验验证了相关光学理论,并相继观察了别的光源,判断出是由于汽车膜中的特殊光栅结构导致的“超长亮线”这一现象,接着搜寻相关资料去找出汽车膜中这一特殊的结构,得出结论。With the development of film technology,there are more and more applications in automotive film,and more and more peculiar phenomena are found in life[7].A super-long bright line will appear when the phenomenon occurs,and a preliminary exploration of the mechanism is carried out.This paper first conducts a preliminary analysis:using optical knowledge analysis and Matlab simulation analysis to infer possible structures and mechanisms-there must be an ultra-fine slit(wire)or grating structure in the optical path from the light source to the human eye,and then experimental verification He studied the relevant optical theory,and observed other light sources one after another,and judged that the phenomenon of“ultra-long bright lines”was caused by the special grating structure in the automotive film.structure,draw conclusions.
