Their oil layer was about 10 microns, or about a hair's width thick.

油层度大约为10微米，相当于头发丝的直径。

And I got it down from 20 microns down to 0.3 microns.

我把它从 20 微米降低了 0.3 微米。

Wow. - Point five microns are stacked together very perfectly.

哇。- 5 微米，非常完美地堆叠一起。

The shorthand for that is PM2.5, which are fine particles that are 2.5 microns or smaller across.

其简称为“ PM2.5”，即直径为 2.5 微米或更小的微粒。

As reference, your hair is 50 microns so this is point 3, it's a fraction of your hair.

作为参考，头发的直径有50微米，所以只相当于头发的一小部分。

But in reality the oil was only 10 microns thick.

但事实上油层度只有10微米。

Why is there a constant isometric force below 2.2 to 2.0 microns?

为什 2.2 2.0 微米以下会有恒定的等距力？

When astronomers talk about dust, they mean tiny grains a micron across.

当天文家说尘埃时，他们指的是直径一微米的微小颗粒。

" N95" means they block at least 95% of particles smaller than 0.3 microns across.

N95意味着它们至少能阻挡95%直径小于0.3微米的粒子。

They noticed many of their pieces of debris sported surface pits around two microns across.

他们发现很多塑料碎片的运动表面周围有大约两微米的凹坑。

And to put this into perspective: a human hair is 100 microns across.

一根头发的直径是100微米。

And that microscope will take images of what's in the water down to about five microns.

显微镜将摄取图像，可以看水里5微米左右的物体。

This is Steve Pawlowski from micron.

这是来美光的自史蒂夫·帕沃夫斯基。

We're looking at one clump of the Chinese purple pigment and the size is around 50 micron.

我们正看的是一丛中国紫色素，大小约 50 微米。

If you do the calculation for oil 10 microns thick the drop should move way slower.

如果你按10微米油层计算，那水滴移动速度应该慢很多。

The capsules were 10-15 microns across-large enough to disrupt the coatings, and thus do more harm than good.

而过去用的胶囊跨度为1015微米，这种跨度足以打乱覆盖层的结构，因此对金属造成的弊大于利。

(ie, smaller than five microns) that may carry viruses much farther through the air than droplets can manage.

（如小于5微米），这些颗粒携带病毒空气中传播的距离可能远远超过飞沫所能达的距离。

We're really good at that, but it's actually very hard to make things from 10 microns to 1,000 microns, the mesoscale.

我们这方面做得很好，但101000微米的范围内 制造物体是非常困难的，这个中等尺度范围。

So we can see most of the typical types of microbial life, from five to two hundred microns, on screen.

所以我们几乎能够看典型的微生物，屏幕上看从5微米200微米的。

Researchers added common shore crabs—Carcinus maenas—to tanks of seawater containing millions of tiny plastic particles, just 10 microns in diameter.

研究人员还表示常见的食草蟹—青蟹身体里所储备的海水中含有成千上万的塑料粒子，直径只有10微米。
