1.引言 CRT常常安装在有严重电磁干扰的环境里(例如、大功率发电机和变压器附近的强磁场)。当CRT处在外磁场中时,其图象就会抖动,虽然这个问题在概念上已经弄清楚了,但未曾作过定量的研究。本文阐明了“用1.5mm厚铝板包封的
1. Introduction CRTs are often installed in environments with severe electromagnetic interferences (eg strong magnetic fields near high-power generators and transformers). When the CRT is in an external magnetic field, its image jitter. Although this problem has been conceptually clarified, it has not been studied quantitatively. This article states "Encapsulated with 1.5mm thick aluminum
