1) the caliber of the focus electrode
聚焦极口径
1.
In order to improve the luminance,the caliber of the focus electrode is increase to improve the utilization factor of the electron beam and ensure electron to bombard on the fluorescence screen entirely.
通过增大聚焦极口径以提高电子束的利用率,保证阴极发射的电子全部打到荧光屏上,以实现提高亮度的目的。
2) radial focusing
径向聚焦
3) focal aperture
聚焦孔径
4) forming electrode
聚焦极;聚焦极
5) Focusing electrode
聚焦电极
6) focus electrode
聚焦极
1.
The results show that changing the potential and diameter of focus electrode,and the space between the grid electrode and focus electrode doesn t affect the electric field seriously,but has strong influence on electron trajectory.
结果表明,聚焦极电位、聚焦极孔半径及聚焦极与栅极间距的变化对锥尖电场影响不大,但对电子轨迹影响很大。
