Their speed goes from eighteen point three micrometers per second up to a whopping thirty point one.

精子的速度从每秒18.3微米上升到30.1微米。

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

我把它从 20 微米降低了 到0.3 微米。

We have at least… at least 100 micrometres of growth per year.

我们每年至少有100微米的增长。

But in reality the oil was only 10 microns thick.

但事实上油层厚度只有10微米。

These cracks are likely only micrometers long.

这些裂缝可能只有几微米长。

Nanoplastics are less than 1 micrometer in size.

纳米塑料的尺寸小于 1 微米。

A normal bacteria measures one to five micrometers long.

正常的细菌有1到5微米长。

A micrometer is one millionth of a meter.

1微米是万分之一米。

Microplastics can be 5 millimeters long at most or as small as one micrometer.

微塑料最长可达5毫米，或小至1微米。

The result is a wire a mere 20 microns across, instead of 50 microns.

结果是，这样的线仅有20微米而非50微米。

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

哇。- 5 微米，非常完美地堆叠在一起。

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

一根头发的直径是100微米。

" 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。

The PM2.5 measurement means the particles are 2.5 microns or less in diameter.

PM2.5的测量的意思是颗粒物的直径小于或等于2.5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，可以看到水里5微米左右的物体。

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

为什么在 2.2 到 2.0 微米以下会有恒定的等距力？

An average-sized bacterium is about 2 micrometers, or 2 millionths of a meter, in length.

平均大小的细菌长度约为 2 微米，即万分之二米。

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

油层厚度大约为10微米，相当于头发丝的直径。

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到典型的微生物，在屏幕上看到从5微米到200微米的。

To put this in perspective, a typical bacteria cell has a width of between 1-10 micrometers.

对比来看，一个典型的细菌细胞的宽度在1-10微米之间。
