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。

The main research work of this dissertation is as follows: Based on the chemical reaction engineering theory and the nitrobenzene electroreduction mechanism, the plate and frame electrolyzer was designed and applied to the process of electroreduction nitrobenzene to p-aminophenol. This dissertation measured the residence time distribution data of the electrolyzer by means of the pulse response method and studied the rule of flow pattern along with the current capacity change. Under different conditions ,this dissertation studied the cyclic voltammetry properties of nitrobenzene on different electrodes by means of the dynamic cyclic voltammetry method and the electrode materials applied to the NB electroreduction have been selected primarily.Baseed on the results of cyclic voltammetry tests, this dissertation used p-electrode systems to measure the steady-state- polarization curves of nitrobenzene on different electrodes in H-type diaphragm cell, and obtained each primary factor s influence rule and the exchange current density value of each electrode.And then on the basis of the conclusions of fundamental researchs upword, the effects of influence factors on the the yield of p-aminophenol and the current efficiency,such as electrode material, current density, quantity of electricity circulated, nitrobenzene concentration . sulpuric acid concentration and so on, have been studied in detail in the systems of hign temperature , strong acidity and oxygen-poorthrough a series of electrolysis experiments in this paper.After all using Pb as anode Monel metal as cathode Dupont Nafion 417 cation-exchange membrane as membrane, this dissertation obtained the optimum technological condition: reaction temperature about 85C, current density 500A m-2, sulphuric acid concentration 20%wt.
