查询词典 diode

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 1905 Fleming produced the first diode in England and in 1906 De Forest made the first triode in the United States .

福雷斯特在美国研制了第一个三极管。

The first stage diode is designed to absorb most of the ESD energy.

第一阶段二极管是为了吸收公共服务电子化大部分精力。

In this design, the leakage current of the diode string can be effectively reduced and a high ESD robustness can be achieved.

所提出的新型电路可以有效地降低二极体串产生的漏电流问题，且具有高的静电放电防护能力。

The results can show the relationship between the diode current and the operation voltage, temperature, photo lux and wavelength, respectively.

由实验结果证明，在不同波长和不同照度的光源下，此模型可成功模拟出反偏光二极体的光电流大小。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
