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.
一盏白炽灯所能达到的最高温度——即最大亮度——是其钨丝熔点的温度。
Polysilicon thin films are deposited by catalytic chemical vapor deposition method. The substrate temperature is 300 ℃ and catalytic hot wire is tungsten filament.
以金属钨为催化热丝，采用热丝催化化学气相沉积，在300℃的玻璃衬底上沉积多晶硅薄膜。
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.
没有采用卤素灯精巧的钨丝，慢慢蒸发直到寿终正寝，氙气大灯的强壮寿命与与汽车一样长。

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.

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.

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).
