日本产业技术综合研究所最近研制成最小刻度为0.2纳米的钻石标尺,可以测量的距离小到不到头发丝直径的十万分之一,这也是目前世界上刻度最小的标尺。这把标尺从外观上看就像一个金字塔,在制作时,研究人员先选择一个光滑的钻石表面作为基座,然后在其上用碳原子一层层堆积起来,看上去就像一级级台阶一样,最终形成了金字塔状的钻 Japan Institute of Industrial Technology recently developed into a minimum scale of 0.2 nm diamond scale, the distance can be measured as small as less than one hundred thousandth the hair wire diameter, which is the world’s smallest scale ruler. This ruler looks like a pyramid from the outside, when making, the researcher first chooses a smooth diamond surface as the base, and then piles up with layers of carbon atoms on it, looks like a first-class step The same, eventually formed a pyramid-shaped drill
