查询词典 cathode

In 1895, Wilhelm Roentgen accidentally discovered that a cathode-ray tube could make a sheet of paper coated with barium platinocyanide glow, even when the tube and the paper were in separate rooms.

1895年，威廉·伦琴偶然发现阴极射线管能使涂有一层氰亚铂酸盐钡的薄相纸发光，甚至当阴极射线管和相纸分别放在不同的房间时也能发光。

Accidentally discovered that a cathode-ray tube could make a sheet of paper coated with barium platinocyanide glow, even when the tube and the paper were in separate rooms.

射线'。''管能使涂有一层氰亚铂酸盐钡的薄相纸发光，甚至当阴极''。'射线'。''管和相纸分别放在不同的房间时也能发光。

The nickel net was settled down on the surface of mSA membrane to realize zero polar distance electrolysis in the cathode room.

将阴极镍网预埋在阳离子交换膜的表面上，以实现阴极室中的零极距电解。

That is less copper anion in the environment. PASP has the effect of corrosion inhibition in hydrochloric acid solution. In addition the potation of cathode summit current turned negative as increasing PASP concentration, and the potential of anode summit current turned positive, it can constrain the corrosion of copper. That is to say PASP is a mixed corrosion inhibitor and can constrain the corrosion of copper surface.

循环伏安测试结果表明： PASP的加入同时抑制了铜表面的阴阳极反应，使阴极峰和阳极峰电流都减弱，说明此环境中的铜离子的含量较少，PASP对铜在盐酸中有缓蚀作用；另外阴极峰电位随着PASP添加浓度的增大而依次变负，而阳极峰电位依次变正，抑制了铜的腐蚀，说明PASP是混合型缓蚀剂，有效地阻止了铜表面的腐蚀。

Key words : corona, high temperature and high pressure, cathode, electrical precipitator, emission current

在不同的温度、压力、电压条件下，对所开发出来的阴极材料进行了电发射特性的试验研究。

He then halved the primary winding, using one-half in the plate circuit and the other half in the cathode circuit.

然后他把初级绕组分成两半，半臂用在屏极电路，另半臂用在阴极线路。

The third winding is coupled between the primary winding and a capacitor to produce a current that controls a variation of a ratio between the focus voltage and the anode voltage as a function of variation in a beam current in the cathode ray tube.

在初级绕组和电容器之间连接第三绕组，从而产生一个电流，该电流用于对作为阴极射线管中电子束电流的变化的函数的聚焦电压与阳极电压之间的比率的变化进行控制。

The new cathode can also be used in manufacturing prismatic cell.

该种电池的持续放电时间比普通碱性锌-锰电池高出2倍以上，将其运用在传呼机、随身听、CDMA手机等方面具有广阔的前景。

The results show that catholic reduction of pyrolusite can be conducted, but the reduction rate is low. The effects of temperature to pyrolusite reduction on the cathode are remarkable. The exchange current density increases with the increase of temperature. The presence of irons is favorable to reduce pyrolusite.

结果表明软锰矿粒可以在阴极上还原，但所占比例较少，温度对软锰矿影响量大，软锰矿在石墨阴极还原的交换电流密度随温度的升高而增大，阴极极化的传递系数很小，添加铁离子有利于软锰矿的还原。

This paper uses an improved charge density method and a more realisticcathode operating mode to simulate the electron optical properties of field emission guns. In the paper a special 6-point quadrature formula has been derived to accurately calculate potentials near theemiter surface and a spherical diode model has been adopted with the cathode operating at the partial space charge limitation.

场发射枪电子光学特性的数值模拟刘志雄，沈文忠，西门纪业（北京大学电子学系，北京100871）本文利用改进的电荷密度法和更接近于实际的阴极工作模型来模拟场发射枪的电子光学性质。

Kauffmann survives, but many of the others are now obscure outside academia: Elizabeth Montagu, a critic—"Queen of the Blues", as Dr Johnson dubbed her—whose portrait by Allan Ramsay shows her looking faintly amused in a froth of lace and pink silk, leaning on a volume by David Hume, the Scottish philosopher and historian; or Anna Seward, a poet who is portrayed turning a page in her Milton—plainly waiting to get back to it; or Elizabeth Carter, poet, classicist, rival of Alexander Pope and translator of Epictetus, helmeted as Minerva, the goddess of wisdom, and carrying a volume of Plato.

经过历史的涤荡，考芙曼的声誉不减当年。而其他的女学者除了在学术界尚有影响以外，已逐渐变得鲜为人知。比如批评家伊丽莎白·蒙塔古。他被约翰森博士称为。在Allan Ramsay为她所做的肖像画上，她身着镶有泡状蕾丝的粉色丝质衣衫，斜斜地倚在由苏格兰哲学家和历史家大卫·修所著的书册上，散发出了令人晕眩的美。再比如诗人安娜·西沃德。在画家笔下，她正在翻动手头的弥尔顿诗篇，很明显，她盼着继续阅读。又比如伊丽莎白·卡特。她既是位诗人，又是古典派作家，与亚历山大·蒲柏齐名，她翻译了的作品。在画中，她扮成智慧女神米诺娃的样子，手执柏拉图的书卷。

When we're not able to maintain mindfulness, we lose track of what's actually going on around us.

当我们无法保持意识时，我们就会迷失现实正在发生的情况。
