Nanometer material gives paint new function .

纳米材料使涂料获得新的功能。

A nanometer is about the width of a strand of dna ; if you design , build , or use functional systems smaller than 100 of these , you 're a nanotechnologist .

一纳米大约只相当于一条dna链的宽度；如果你设计、建立或使用小于100纳米的机能系统，你就是一个纳米技术专家了。

Even the megadalton , or one million daltons , is a tiny unit of measure-a gold particle five nanometers across weighs in at just a few megadaltons . ( One nanometer is a billionth of a meter . )

即使百万道尔顿也是份量极小的单位：一颗5纳米（1纳米=十亿分之一米）的金颗粒的质量就有好几百万道尔顿。

Thanks to its low temperature and that nanometer gap , pairs of electrons could flow between the two plates without friction .

由于低温和微米间隔的作用，电子对可以在两块铝片之间流动而没有摩擦。
