1·To see anything smaller than 500 nm, you will need an electron microscope.
为了看任何小于500纳米的物体，你需要一个电子显微镜。
2·However, instead of heating the entire sample, the researchers used a hot atomic force microscope (AFM) tip to convert very narrow ribbons, measuring just 12 nm across, into reduced graphene.
然而，研究人员并非采用加热整个样本的方案，而是使用了原子力显微镜(afm)一个加热探针去转换出一条仅有12纳米宽的导电带。
3·With 60Nm of torque, the bike has a lot more grunt than a typical electric hub-motor installed in bicycles.
由于60纳米的扭矩，这种自行车比典型的安装了电动旋翼叶毂发动机的自行车有更多动力。
4·Most chips produced commercially currently operate at the 45nm scale, while cutting edge techniques are able to produce chips that operate at the 22 nanometer level.
目前大多数商业化生产的芯片多在45纳米，而最先进的技术所能生产的芯片在22纳米的水平。
5·The power of a light microscope is limited by the wavelength of visible light, which is about 500 nm.
光学显微镜的放大倍数受限于可见光的波长，大约500纳米。
