課程:《納米是什么》
Well, Mike, nowadays there's much talk about nanometer. But what on earth is it?
麥克,現(xiàn)在好多人都在談?wù)摷{米。它到底是個(gè)啥呀?
Nanometer is a length scale. It's one billionth of a meter, roughly ten times the size of an individual atom.
納米是個(gè)長度單位。一納米等于十億分之一米,大概比一個(gè)原子大10倍吧。
Hmm...it's hard to figure out the exact size, I'm afraid.
嗯…恐怕還不太容易想象得出它得具體大小呢。
Well, let's make it this way. For comparison, 10 NM is 1000 times smaller than the diameter of a human hair.
這樣說吧。10納米比一根頭發(fā)直徑得1/1000還短。
There are as many nanometers in an inch as there are inches in 400 miles.
一英寸所含得納米數(shù)量等于400米所含得英寸數(shù)。
I see. Thank you.
這樣說我就明白了。謝謝啊。
明天繼續(xù),早上7:00,不見不散。
