摘要
从固体材料的热发射机理开始分析,引出彩色显像管中最常用的氧化物阴极和浸渍式阴极,并对它们的结构、发射机理、激活过程以及工作做了详尽的分析和对比,并对其前景作了可观的描述。
This report analyzed the heat emission mechanism of solid materials, and then discussed the oxide cathode and impregnated cathode for CPTs. The cathode structure, emission mechanism, activity process, and working conditions are also analyzed and compared in detail.
