偏转磁场 meaning in English
deflecting magnetic field
deflecting magntic field
magnetic deflection field
Examples
- The effect on display characteristic made by thermal deformations of the shadow mask is comprehensively investigated . by using the electron beam distribution automatic measurement system with a micro - deflective coil , a concave spot in luminance distribution can be get . it changes its position when the shadow mask changes its form
本文系统全面地分析了传统荫罩的各类热变形对显示屏特性的影响，利用本文研制的电子束亮度分布自动测试系统，附加一个微偏转磁场，使相邻两电子束打在同一颜色的荧光粉条，并形成一个亮度凹点，当荫罩变形时，凹点位置作相应的位移，以此原理跟踪测量凹点位移量，即可得到色纯漂移动态变化曲线。 - The shadow mask is the critical component of the colour picture tube and the important component for the choice of colour , its function concentrates on the limitation of electronics bound diameter and the screening direction , the electronics bound which is sent by the electronics gun goes scanning , during the scanning process , we should guarantee every bound gathering into the small holes situated on the screen , then these bounds will point to the regularized position through the small holes on the flat mask , and then three basic colours will be produced , at the same time , those useless electronics will be blocked by the mask board
平板荫罩是彩色显像管的关键部件之一，是一个重要选色元件，其作用是限制电子束直径和上屏方向，由电子枪发射的电子束在偏转磁场的作用下进行扫描，扫描过程中必须使每个电子束只能射中荧光屏上的为该束指定的那些小孔上会聚，并通过荫罩上诸多的小孔分别打到各自对应的荧光质点上，发出三种基色（红，绿，蓝） ，而无用的电子则被荫罩板截获。
