Edison's lab put a lot of effort into making a bulb with a platinum filament, but that work went nowhere, because platinum has a relatively low resistance.
爱迪生的实验室为制造铂丝灯泡付出了大量的努力,但这些投入都白费了,因为铂的电阻相对较低。
In 1840, James Bowman Lindsay put a platinum filament into a glass bulb and removed most of the air so that the filament wouldn't oxidize, and thus the first working light bulb was created.
1840年,JamesBowmanLindsay将铂金细丝放入玻璃灯泡,并抽走所有的空气以防止铂被氧化,这样第一个工作的电灯泡被创造出来了。
Originally Edison used platinum alloys for the filament, in the belief that carbon was impracticable.
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。
