二极管

It was found the brightness of each primary color LED device has changed with the change of temperature.

通过对RGB三基色发光二极管温度特性的测试和分析发现，随着环境温度的变化，每种基色的LED亮度与常温时的亮度相比都会发生一定程度的偏移，且其偏移量不相同，导致了图像白场平衡的失真。

The only condition under which the preselector made no difference is when measurements are made with a high tunnel-diode gain.

1只有在用高增益的隧道二极管来测试时，用不用预选器才显得无关紧要。

A novel laser ranging method use Geiger mode APD arrays is introduced in this paper.

提出了一种基于盖革模式下雪崩二极管阵列作为接收器件的激光测距新技术。

The photoelectric devices fabricated from organic polymers, including organic lightemitting diodes, field effect transistors, photovoltaic cells,etc, have attracted people's huge interests.

基于有机材料的光电子器件，如高聚物发光二极管、场效应管、太阳能电池、可充电的电池等引起了人们广泛的兴趣。

Somewhat less obvious is the fact that photodiode leakage and photovoltaic cell internal losses are also functions of terminal voltage.

此外，光电二极管的漏电流和光电池的内部损耗也是其端电压的函数。

And cleaning optical mouse, the main wash attached to the LED and a phototransistor on the dirt.

而清洗光电鼠标，主要清洗附着在以光二极管和光敏三极管上的污垢。

With the optical chopper sensor composed of launch diodes and phototransistor.

传感器由发射二极管和光敏三极管组成的光断续器。

When using the optical mouse, mouse pad to keep it in a better cleaning of the photosensitive state, in order to avoid the dirt attached to the LED and phototransistor, the light receiving shelter.

使用光电鼠标时，要注意保持鼠标垫的清洁使其处于更好的感光状态，避免污垢附着在以光二极管和光敏三极管上，遮挡光线接收。

The use of optical mouse, it is necessary to pay attention to maintaining a clean plate of the sensor so that it is in a better state, in order to avoid the dirt attached to the LED and phototransistor, the light receiving shelter.

4使用光电鼠标时，要注意保持感光板的清洁使其处于更好的感光状态，避免污垢附着在以光二极管和光敏三极管上，遮挡光线接收。

Optical mouse lens system of the launch and the combination of components is one, fixed in the shell on the mouse, and the phototransistor is fixed in the circuit board, the location of the two must be very precise, manufacturers in the calibration of the location with hot melt adhesive to a fixed LED components in the lens, and if in use, the mouse has been touched or fall too much vibration, it is possible to make hot melt off, shift light-emitting diodes.

光电鼠标的发射及透镜系统组件是组合在一体的，固定在鼠标的外壳上，而光敏三极管是固定在电路板上的，二者的位置必须相当精确，厂家是在校准了位置后，用热熔胶把发光管固定在透镜组件上的，如果在使用过程中，鼠标被摔碰过或震动过大，就有可能使热熔胶脱落、发光二极管移位。

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
