二极管

ABSTRACT The laser diode pumped solid state lasers are that solid state laser, used laser diode instead of flash lamp to pumping laser gain materials.

激光二极管泵浦的固体激光器是用激光二极管代替闪光灯去泵浦激光晶体的固体激光器。

A LIGHT-EMITTING DIODE is a diode which, when forward biased, produces visible light.

一有机电致发光二极管是二极管，当着偏见，产生可见光。

When the diode is forward biased, it begins to conduct with only a small forward voltage across it, which is on the order of one volt.

图 1-4A-1 为二极管的线路符号。二极管正向偏置时导通，并有 1 伏左右的正向压降。

They can be interconnected to form single phase or three phase bridges and the single diode module can be used in conjunction with the thyristor modules as a freewheel diode.

它们可以相互连接，形成单相或三相桥和单二极管模块可作为一个飞轮二极管晶闸管模块配合使用。

In computers, these diodes are primarily germanium or silicon crystals.

在计算机中，这些二极管根本上是锗或硅晶体二极管。

Organic light-emiting devices are extremely sensitive to vapor and oxygen. The influence of inleakage of oxygen and vapor on OLED's lifetime was serious. Thus, encapsulation is very important to an OLED device. Research status of encapsulation technology of OLED on different substrate and cover.

有机电致发光二极管对水汽和氧气非常敏感，渗入发光二极管器件内部的水汽和氧气会对器件寿命产生严重的影响，因此OLED的封装是制造OLED的关键技术之一。

Through analysis to multilevel invertor a method of switching angle control for Diode-clamping Multilevel Inverter is introduced. The quantity of wave for output voltage is improved and the content of harmonics is reduced. And a design is carried on to realize the control mode based on TMS320F2407DSP.

通过分析多电平逆变器的拓扑结构，选择二极管箝位型多电平逆变器为研究对象，提出在二极管箝位型逆变电路中实现开关角控制的方法，该方法减少了谐波的含量，改善了输出电压的波形，并以TMS320F2407DSP为平台进行了设计实现了该控制策略。

With its simplest structure –PN junction, the diode has been studied in this paper as an example for making an explanation on the physical quantity and relevant mathematical expression corresponding with respective parameter of SPICE model in the library of simulation software.

文章以结构最简单的二极管PN结作为研究对象，旨在对与仿真软件的元件库中各元件的SPICE模型参数相对应的物理量及数学表达式加以解释和说明，并就这些参数如何反映二极管的电气特性这一问题作了一定的分析。

To better match the characteristics of the two PN junctions (the diode junction and the transistor base-emitter junction), a transistor may be used in place of a regular diode, like this

为了更好地匹配两个PN结地特性（二极管PN结和晶体管发射结），可以用晶体管代替二极管，如图。

Remember that the base-emitter junction of a BJT is nothing more than a PN junction, just like a diode, and that the "diode equation" specifies how much current will go through a PN junction given forward voltage drop and junction temperature

其实，BJT的发射结不过是个PN结，就如同二极管。因此流过PN结的电流与其正向压降的关系也符合"二极管方程"

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
