溫馨提示:易賢網小編為您整理了“口語交際:納米到底是什么? What on earth is nanometer?”,方便廣大網友查閱!

A:Well, Mike, nowadays there's much talk about nanometer. But what on earth is it?

麥克,現在好多人都在談論納米。它到底是個啥呀?

B:Nanometer is a length scale. It's one billionth of a meter, roughly ten times the size of an individual atom.

納米是個長度單位。一納米等于十億分之一米,大概比一個原子大10倍吧。

A:Hmm...it's hard to figure out the exact size, I'm afraid.

嗯…恐怕還不太容易想像得出它的具體大小呢。

B:Well, let's make it this way. For comparison , 10 NM is 1000 times smaller than the diameter of a human hair. There are as many nanometers in an inch as there are inches in 400 miles.

這樣說吧。10納米比一根頭發(fā)直徑的1/1000還短。一英寸所含的納米數量等于400米所含的英寸數。

A:I see.Thank you.

這樣說我就明白了。謝謝啊。
