三斜板系统电子束偏转量的计算

The Theoretical Analysis and Calculation of the Amount of Electron Beam Deflection of an Electrostatic Deflection System Consisting of Triple-deflective Deflection Plates

本文论述具有三重偏斜偏转板静电偏转系统(三斜板系统)的现代示波管中电子束在荧光屏上偏转量的理论分析与计算。基于物理学中的电场理论和13SJ38J型示波管的典型结构与参数,文中推证出了和实测数据吻合得很好的电子束偏转景的理论公式以及计算机的输出结果。

A definitive conclution concerning the thecretical analysis and calculation of the amount of electron beam deflection for an electrostatic deflection system made up of tripledeflective deflection plates in modern display tubes had not been known. Based upon the electric field theory of physics and the typical structure and parameters of type 13SJ38J display tube, this paper gives the conclusive formulas for calculating the magnitude of electron-beam deflection. The calculated results and the data obtained from experimental measurements have heen found in clo se consistence.
