They might be 100 nanometers or so in diameter, whereas, a cell is ten microns or so in diameter.
直径只有一百纳米左右,而一个细胞的直径是十微米左右
And, that's a good thing to know because if you come out with an answer that's somewhere near the diameter of the universe and it's supposed to be the diameter of an atom, then you will know that you probably made a mistake.
这是我们需要知道的,因为当你做一道题得到的答案,是宇宙的直径,而正确答案是原子直径时,你能很快发现你的错误。
In addition, if we compare this to the diameter of an atom, which is on the order of somewhere between one and ten angstroms, now we're seeing that, in fact, this wavelength is significantly larger than its environment.
另外,如果我们把它,与原子的直径相比,原子直径近似1到10埃米之间,我们现在来看看,事实上,这个波长比它所处的环境大很多。
