本文用PHI—550电子能谱仪,对两种不同厂家生产的显象管中氧化物阴极基金属表面进行了研究。发现钡的“反扩散”现象是影响阴极发射性能的重要因素。
In this paper, PHI-550 electron spectrometer was used to study the cathode surface of the oxide cathode metal of two kinds of kinescopes produced by different manufacturers. Barium was found to “anti-proliferation” phenomenon is an important factor affecting the cathode emission performance.
