很快，该实验室制造出持续40小时的碳丝灯泡。
我们现在的钨丝灯泡比老的碳丝灯泡好，钨丝灯泡更亮、更耐久。
Our tungsten lamps are better than the old carbon lamps. They are brighter and they last longer.
起初，它致力于研制碳丝灯泡，并最终成为本世纪初欧洲最大的制造商。
In the beginning, it concentrated on making carbon-filament lamps and by the turn of the century was one of the largest producers in Europe.
随着电流的增加，金属丝灯泡的电阻是增加的，而碳丝灯泡的电阻是减小的。
The resistance of the metal-filament lamp increases, and that of the carbon-filament lamp decreases with increase of current.
