纳米是一种长度单位,1纳米是1米的十亿分之一,1纳米相当于一根头发丝的6万分之一。2000年9月28日,中科院副院长白春礼院士在人民大会堂举行了一次生动的纳米科技应用报告,白春礼副院长演讲前将自已的白纱领带解下, 倒上酱油、可乐、咖啡、牛奶、墨水等各色液体。1个钟头后,白院长将领带提起,所有污渍像倒在荷叶上的水珠一样顺势全部滑落,没有一点渗入领带,此时,全场掌声雷动。
Nanometer is a unit of length, 1 nanometer is one billionth of a meter, and 1 nanometer is equivalent to 60,000th of a hair. On September 28, 2000, Academician Bai Chunli, vice president of the Chinese Academy of Sciences, held a vivid report on the application of nanotechnology in the Great Hall of the People. Before his speech, Vice President Bai Chunli removed his white gauze tie and poured soy sauce, cola, coffee, Milk, ink and other colored liquids. An hour later, President White lifted his tie and all the stains slipped down like drops of water on the lotus leaf without any infiltration into the tie. At this moment, the audience applause thundered.
