（１）超级灯：俄罗斯科学院物理研究所的研究人员研制成一种大功率的“超级灯”。由于这种灯的功率高达５万瓦，看上去如同太阳，因此必须戴上墨镜才能观察该灯光。 常用的白炽灯有一个致命的缺点，就是当灯泡中的灯丝烧断后，寿命便告结束。气体放电灯虽然没有灯丝，使用电极 (1) Superlight: Researchers at Institute of Physics, Russian Academy of Sciences have developed a high-power “superlight.” Because of this lamp’s power of up to 50,000 watts, it looks like the sun, so you must wear sunglasses to observe the light. Common incandescent lamp has a fatal flaw, that is, when the filament in the lamp blown, the life will end. Gas discharge lamp although there is no filament, the use of electrodes
