碳导电，并且电阻值高，可以做成细灯丝。
Carbon conducts electricity, has a high resistance and can be shaped into thin filaments.
这个过程无需高温，而且用大量纳米碳管取代了单金属灯丝释放电子。
This dispenses with the heat. Also, instead of having a single metal filament release the electrons, it relies on myriad carbon nanotubes to do the same thing.
本文利用热灯丝化学气相沉积法(HFCVD)制备了纳米量级的碳薄膜材料，对它的电学性质及场发射性质进行了详细的研究。
In this dissertation, extensive researches on the electrical and field emission properties of nano-carbon films prepared by hot filament chemical vapor deposition (HFCVD).
