摘要
应用多极场理论对彩色显像管中偏转散焦进行了分析 ,结果表明 ,多极场展开式中的四极场分量是影响偏转散焦的主要因素 ,对三束的分析应分别考虑电子束在偏转场中的位置。
Deflection defocus of color picture tubes was analyzed in multipole field theory.The analytical results show that quadruple term of the deflection field significantly affects deflection defocus.The spatial positions of the three electron beams in the deflection field should be considered in the analysis of each electron beam.Higher order harmonics may also be of importance in practical deflection system analysis.
