二极管

The value of active energy is determined to be 0.82 eV and mean lifetime in practical operation at driving current of 100 mA and an ambient temperature of 298 K is over 106 h, and high reliability and long lifetime required for light source of FOG are confirmed.

计算出了器件的激活能平均值约为0.82 eV，SLD管芯在室温下的工作寿命超过106 h，可以满足光纤陀螺用光源的寿命要求。对影响SLD管芯可靠性的因素以及管芯的退化机理进行了分析，为研制高可靠性的超辐射发光二极管提供了理论基础。

Ultravioles/visible spectrophotometers, including diode array detectors, are the most commonly employed detectors.

紫外/可见光度计，包括二极管阵列检测器是较为常用的检测器。

Radiation from a fiber coupled diode (core diameter 0.4 mm, N.A. 0.3) is coupled into Tm5% at.,Ho(0.5% at.∶GdVO4 crystal by a pair of achromatic lens for end pumping. Output power of 3.6 W at 2.048 μm is obtained under pump power of 14 W and emission wavelength of 794 nm. The optical-optical conversion efficiency is 25.7% and slope efficiency is 26.6%.

在液氮制冷晶体条件下，利用光纤耦合激光二极管及消色差光学耦合系统端面泵浦双掺5％Tm，0.5％Ho∶GdVO4晶体，在泵浦功率14 W、泵浦波长794 nm时，实现了2.048 μm激光输出，连续运转输出功率3.6 W，相应的光光转换效率为25.7％，斜率效率26.6%。

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。

The object for each of these lenslets is the image of the LED that would be formed by the Fresnel lens.

采用高亮度发光二极管，用菲涅尔透镜和柱透镜阵列使光线集中在用户眼睛上，大幅度提高图像亮度，由于左右眼看到的图像不一致，产生视差，形成立体感。

Her lamps are surprising and poetic, made of led with plexiglas or paper, they create a very soft atmosphere.

她的灯具都设计得很令人意外，充满诗意。使用发光二极管及树脂玻璃或者纸质材料，这些灯具营造了非常柔和的气氛。

You can be sure if Hamamatsu is selling a "methane" LED, someone is using it for a CH4 instrument.

你可以确认一下是否Hamamatsu 正在卖一种叫甲烷发光二极管的产品，有人将它用在CH4 设备上面。

I have attached the Hamamatsu 1.65 um LED which has been developed for CH4 application.

我已经附上了1.65 微米的Hamamatsu 发光二极管，此管已通过CH4应用改进过。

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。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
