华盛顿专电 一种直径十微米的塑料微球粒,最近在美国国家标准局出售。三千万颗肉眼很难分辨的透明微球粒,装在贴着“太空制”标签的小玻璃瓶里。这是世界上第一批在太空中制造的商品。制造这种微球粒的原料,是生产目前市场上普通的透明塑料杯等家庭用具的聚苯乙烯,价格每磅只需半美元左右。但是,它到太空中“旅行”一趟,被加工成这种微球粒后,身价猛增,每磅售价高达二百万到七百万美元,大大超过“一本万利”。 Washington, DC A plastic microsphere with a diameter of 10 microns was recently sold in the US National Bureau of Standards. Thirty million transparent microspheres, which are difficult to distinguish with the naked eye, are housed in small glass bottles labeled “Space”. This is the first batch of goods manufactured in space in the world. The raw material for producing such microspheres is polystyrene, which is a common home appliance for the transparent plastic cups currently on the market, and the price is only about half a pound per pound. However, when it was “traveled” into space, it became a microsphere and its value increased rapidly. The price per pound was as high as two to seven million US dollars, which was much higher than “one profit”.
