半导体器件没有灯丝，因此也不需加热功率或加热时间。
Semiconductor devices have no filament or heaters and therefore require no heating power or warm-up time.
他尝试了一千多种不同的灯丝后才找到一种适合的材料。
He tried more than a thousand different filaments before he found one that he could use.
爱迪生不相信碳可作灯丝用，所以一开始就用铂合金作灯丝。
Originally Edison used platinum alloys for the filament, in the belief that carbon was impracticable.
用于制造双螺旋或三螺旋荧光灯丝、普通白炽灯丝、支架丝等。
Applied for making coiled-coil or trispiral CFL filament, incandescent filament and support.
左边的阴极被灯丝加热到高温，同时电子从阴极表面蒸发出来。
The cathode at the left is raised to a high temperature by the heater, and electrons evaporate from its surface.
爱迪生试验了1600种材料，然后才找到适于制造灯丝的一种。
Edison tried 1600 substances before he found a right one for filament inside his electric bulbs .
除了通过“世纪灯”灯丝的电流微弱外，这盏灯长寿的秘诀在于人们很少关掉它。
Apart from the tiny current trickling through its filament, the secret of the Centennial Light's long life is that it has rarely been turned off.
经过灯丝产生可见光的能量只占总能量的2%，余下的大部分以热能的形式丢失。
The amount of energy pushed through a filament that actually emerges as visible light is around 2 percent — most of the rest is lost as heat.
爱迪生因而测试了6,000种纤维，并遍寻世上最适合造灯丝的材料。
So, Edison tested 6,000 fibres, and searched the world for "the most suitable filament materials."
事实上，氩元素的浓度相当高，如果房间里有电灯泡被打破，灯丝却还可以继续发亮。
In fact, the argon would be so thick that if a light bulb inside the room were to break, the filament would keep glowing.
由于灯丝电阻受温度影响而呈非线性变化，因而计算的结果一般误差很大。
However, because the filament resistance varies nonlinearly under the influence of temperature, the error of the calculating result is always great.
试想下灯泡，如果接通了电流，灯丝会变热继而发出不同颜色的光-从红到黄再到蓝色。
Think about a light bulb; if you apply a current, the filament gets hot and begins to give off light of different colors - red then yellow then blue.
