tungsten filament

基本解释

The highest temperature—and thus the brightest light—that an incandescent lamp can achieve is the melting point of its tungsten filament.
一盞白熾燈所能達到的最高溫度——即最大亮度——是其鎢絲熔點的溫度。
Polysilicon thin films are deposited by catalytic chemical vapor deposition method. The substrate temperature is 300 ℃ and catalytic hot wire is tungsten filament.
以金屬鎢爲催化熱絲，採用熱絲催化化學氣相沉積，在300℃的玻璃襯底上沉積多晶矽薄膜。
Lacking the halogen’s delicate tungsten filament, which slowly evaporates with use until it finally “blows”, xenon discharge lamps are robust enough to last at least the lifetime of the car.
沒有採用鹵素燈精巧的鎢絲，慢慢蒸發直到壽終正寢，氙氣大燈的強壯壽命與與汽車一樣長。

The solution was a vacuum cap that sits over the whole unit, much like the glass globe surrounding the tungsten filament in a flashlight bulb.
FORBES: Pip-squeak Power Plant
Edison bulbs function by making a Tungsten filament very hot, and a hot object glows: radiating energy on a broad spectrum of wavelengths, only a small part of which is visible to the eye.
FORBES: LED Light Bulbs Mature At Last
As with many other products--including tungsten-filament lightbulbs, X-ray machines and jet engines--GE bought patents from an inventor to get into the turbine business, then refined the design and manufacturing techniques ( see time line).
