显像管发射小的跟踪分析

Tracking and Analysis of Small Emission of the Kinescope

本文对黑白显像管发射小进行了跟踪分析，认为阴极涂层脱落和管内真空度不良是导致显像管发射小的主要原因。

The tracking and analysis for the small emission of the black and white TV display tubes are presented in this paper. A portion of the oxide coating fallen off from the cathode basis and the low vacuum inside the tubes are the main factors to cause the small emission of TV display tubes.
