偏转系统

Aberration of electronic lens made by electron gun and aberration of magnetic deflection system made by dy are comprehensively investigated , so is the shadow mask ' s effect on electron beam landing screen error . the conclusion can be get that , because the distribution of electron beam landing screen ( distribution of luminance ) is affected by many kinds of factors , it cannot get the correct function by calculation , and should be get by measurement instead
全面分析了cpt电子枪发射系统形成的电子透镜像差与磁偏转系统形成的偏转像差；分析了荫罩的自身厚度与位移对电子束着屏的影响，并由此得出结论，着屏电子束分布(即亮度分布)受着许多因素的影响，理论分析是半定量的，着屏电子束分布需要用精确的测量仪器来测量。
