小型打印器不久可能变得更加小巧玲珑得多。这要感谢美国密执安大学和多伦多大学的研究人员设计出的一种纳米自来水笔。1纳米只有1米的10亿分之一,你想这种自来水笔写出的字会有多么小。研究人员说,他们用一种称为“原子打气筒”的东西可以把一个个原子喷射(书写)到表面上。
Small printers may soon become much smaller and more compact. Thanks to the design of a nano fountain pen by researchers at the University of Michigan and the University of Toronto. 1 nanometer is 1 billionth of a meter and you want the pen to write the word how small. Researchers say they can spray (write) one atom onto the surface using something called an “atomic pump.”
