查询词典 cathode current

The nature of the Crookes tube " cathode ray " matter was subsequently identified by British physicist Sir JJ Thomson in 1897, [ 2 ] and dubbed "plasma" by Irving Langmuir in 1928, [ 3 ] perhaps because it reminded him of a blood plasma .

的性质克鲁克斯管&阴极射线&的问题，后来查明的英国物理学家先生杰杰汤姆森于1897年， [ 2 ]并称为&等离子体&的欧文朗缪尔于1928年， [ 3 ]也许是因为他想起了血浆。

While still at school and working with his father, John,a general practitioner and a friend of William Crookes (also apioneer investigator of cathode-ray phenomena), he completed theapparatus within a year.

原文说的是：在1896年1月，英国首次报道了对X射线的发现；刘兵给看成了英国在这一年有第一篇关于X射线的报告。原文说的是：雷诺兹与其父一起工作，其父是克鲁克斯的朋友；刘兵给译成了克鲁克斯是雷诺兹的朋友，并参与该项工作。

While still at school and working with his father, John, a general practitioner and a friend of William Crookes (also a pioneer investigator of cathode-ray phenomena), he completed the apparatus within a year.

此文据说收入新近出版的刘兵著《剑桥流水》（河北大学出版社2003年版）一书。我没见过此书，不知在书中是否有改动，这里根据的是《中华读书报》刊登的版本。

The cathode-ray tube or "Crookes' tube" like object depicted in scenes from the temple of Hathor at Dendera may depict a relativistic source of these heavy electrons - which could drastically expedite the magical processes which involve these particular tubes.

阴极射线管或&克鲁克斯管&就像来自Dendera哈索尔神庙场景里描述的物体可能描述这些重电子一个相对论的来源点-重电子可以激烈加速这奇异的局限在这特别管里的作用过程。

The earliest version of the CRT was invented by the German physicist Ferdinand Braun in 1897 and is also known as the Braun tube.[1] It was a cold-cathode diode, a modification of the Crookes tube with a phosphor-coated screen.

还是从这里开始普及吧，CRT和放电管区别很明显，放电管是用来观察放电效益，内部充气，根本没什么成像效益，和CRT就完全不是一回事，在说说你的美籍俄裔科学家，这家伙1907年用CRT成像，但当时他是沙俄工程师，俄国内战跑到美国去。

In the first decade of the new century, Lee de Forest inserted a grid in the tube between the anode and cathode.

在新世纪的第一个十年，Lee de Forest往电子管的阳极和阴极之间插入一层栅格。

So, our main work is to obtain a satisfactory electron beam with diameter about micrometers by means of choosing a suitable LaBe cathode electron-gun system and a suitable focusing system.

电子束打靶产生X射线已经是很成熟的理论，因此，本论文的理论研究重点是选择合适结构的电子源系统与合适结构的聚焦系统并将电子束会聚为微米级的细小束斑。

The former consists of LaBe crystal cathode, Wehnelt grid and an accelerating anode, and the latter is comprised of two equal radius concentrating cylinder electrodes.Its well known that the x-ray radiation emitted by electron-beams acting on metal target surface has well developed for about 100 years.

LaB_6电子枪发射的电子束经过静电聚焦系统，被会聚为微米级的电子束斑，该微束斑电子束与固体金属靶相互作用，产生出微束斑的X射线，从而形成微束斑X射线源。

Current A cold current of air came in when the door was opened.

在她平静的生活中，没有任何的骚扰。

A current of air from a fan; a current of spoken words.

从风扇中吹出的一股气流；一通讲话

My father is over 60 years old, and he lifts weights every day.

我爸爸六十多岁了，他每天都练习举重。

Then in a serious tone she declared:"It doesn't pay, dear boy, to look like a ninny with one's wife the first night."

两眼湿润了，她把身子蜷得很小，这样似乎可以更好地闻闻自己。
