灯丝

Unlike Halogen lamps, High-Intensity-Discharge lamps don't have a filament but create light by the arc between two electrodes.

不像卤素灯泡，高强度放电灯没有一个灯丝，但创造轻，由弧之间的两个电极。

Although the electron the that in the past few years development the is sit up current stabilizer may be achieved the cold boot ,Yet also injure the active material on the heater easily but causes very fast blackout but the failuries of fluorescent tube two ends .

近年来发展起来的电子镇流器虽然可以实现冷启动，但也很容易击伤灯丝上的活性物质而使灯管两端很快发黑而失效。

A new view of two very well-known galaxies has revealed they are connected by faint, starless filaments of hydrogen gas, which trace back to a very high-speed intergalactic collision.

最近，天文学家们对两个非常熟悉的星系进行了一次观测，发现它们之间由氢气构成的灯丝状结构连接，灯丝状结构光线暗淡，其中没有恒星。

In electronics, a vacuum tube or thermionic valve or just valve, is a device generally used to amplify, switch or otherwise modify, a signal by controlling the movement of electrons in an evacuated space.

真空管是一种电子设备，由抽真空的容器组成，它具有发射电子的阴极（旁热式是由灯丝加热，直热式则灯丝就是阴极）和工作时通常加上高压的阳极。阴极和阳极之间，自阴极算起，第一个电极称为栅极，再增加一个电极则称为帘栅极。

The calculation will be convenient and its result will be accurate with the volt-ampere characteristics curve of the filament resistance.

灯泡不发光时，灯丝温度只有几十度，而正常发光时却能达到 2 0 0 0℃以上。灯丝电阻随温度的升高而增大，且明显地呈非线性关系。

When end surface is neglected, the reflective energy will return to the filament efficiently if the filament is at the centre axis of the columniform lamp shell. 3 Compared with the straight tungsten filament that has a smooth surface, the helical one obtains higher absorbance which can achieve 0.6~0.7 under the actual screw pitch measurement.

当灯的管径为10 mm，而灯丝外径为1.5 mm时，节能可达12%到13%。2）对圆柱形灯外壳，在不考虑端面影响时，光源的灯丝若处于外壳的中心轴上，则反射的能量会有效地返回灯丝。3）螺旋结构的灯丝比表面光滑的直钨丝有更高的吸收率，灯丝绕成螺旋后在现行的螺距尺寸下吸收率能达到

The main content consists of the following aspects: The essential techniques of rate control are introduced, such as the principle of rate detection by quartz crystal﹑the relationship between filament emission current and filament temperature﹑the temperature dependence of material evaporation characteristic﹑the electron beam focalizing characteristic and the theory of rate closed-loop control.

主要内容包括以下几个方面：围绕电子束蒸发速率控制综合了速率控制的相关技术，比如蒸发速率石英晶振探测的原理﹑灯丝发射电流与灯丝温度的关系﹑膜料蒸发特性与蒸发温度的关系﹑电子束焦斑聚焦特性及速率闭环控制的原理。

B DC high voltage power supply circuit short circuit, high voltage filter capacitor should check whether the breakdown leakage current, filament transformers for filament winding of whether the earth leakage, tube bracket fixed capacitor (high-frequency coupling capacitor) whether the breakdown leakage, rectifier diodes have breakdown short-circuit phenomenon

b 直流高压供电回路短路，应检查高压滤波电容是否击穿漏电、灯丝变压器的灯丝绕组是否对地漏电、电子管支架固定电容是否击穿漏电、整流二极管是否有击穿短路现象

The Edison 20 yearsold raise one's head start to study the electric lamp, the lasted morethan 10 years, he has successively selected the bamboo cotton andkapok, the graphite, the tantalum...... And so on over a thousandkind of different matter make the lamp silk material to carry on theexperiment, often passes 霄 until dawn, some he and assistantsunexpectedly continuous working 5 day and nights. In 1879 Edison withthe carbon silk took the incandescent lamp silk, and lights for 40hours.

爱迪生20岁出头开始研究电灯，历时10余年，他先后选用了竹棉、石墨、钽……等等上千种不同物质作灯丝材料进行试验，时常通霄达旦，有一次他和助手们竟连续工作5昼夜。1879年爱迪生用碳丝作为白炽灯丝，并点燃40小时。

Working in this way, the problem to preheat the filament before starting the lamp would be solved, yet the power dissipation of starting circuit during the entire period of lamp lighted would dissipate no more.

智能预热启动是这样的：通电后，先对电极灯丝进行几秒时间的预热，然后将灯启动点亮，灯亮后启动电路自动关闭，这样既解决了可将灯丝先预热后才启动点亮灯的问题，又解决了灯在燃点过程中，启动电路仍要消耗功率的问题。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
