电子束偏转

In the design of electron beam deflection system with a large scanning field, determination of aberration is a practical problem.

电子束大扫描场偏转系统设计中，像差的确定是一个必须解决的实际问题。

Displays around the magnetic field will be easy to produce items, such as multimedia speakers, a variety of peripherals, such as used in transformers, the magnetic field will affect the direction of the electron beam deflection.

显示器的周围会出现易产生磁场的物品，如多媒体音箱、各种外设所用的变压器等，这些磁场都会影响电子束的偏转方向。

Outlines the J2476 electron beam demonstration to use the JG-4 gasification electrostatic deflection cathode ray demonstration tube i.e.

J2476型电子束演示器采用JG-4充气型静电偏转阴极射线演示管。

The numerical calculations under relativistic correction and non-relativistic correction show that the difference of the deflection distances is about 61.4 mm,and the difference of the electron pulse widths is about 65 fs.

计算结果显示，在忽略了电场的边缘效应等因素后，电子束轴向速度的相对论修正与否对偏转距离和电子束脉冲宽度的影响分别达到61.4 mm和65 fs。

The good characteristics of the deflection system of electron gun can be obtained by optimizing the velocity and the location of emitting electron beam and by the aclinic emission of the electron beam, that can be achieved by making the end of the anode and the middle part of the cathode level.

研究结果表明：电子枪阳极板端点与阴极灯丝中心点保持水平可满足电子水平出射；非均匀分布的磁场对e型电子枪中电子束具有良好的聚焦作用；所设计的偏转聚焦系统在电子束流为50~100 mA时，束斑小于3 mm。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
