This photo records the amazing beauty of dust particles floating in the sunlight.

张照片记录了在阳光中漂浮尘埃微粒惊人美。

This makes the core a thick soup of ultra-hot subatomic particles.

太阳核心变成一锅极热亚原子微粒浓汤。

These sand-sized particles emit ionizing radiation, capable of separating electrons from molecules and atoms.

些沙粒大小微粒发出离子辐射，能够分子和原子电离。

It was chemical engineer and material scientist Yendry Corrales-Urena who noticed the silica-based microparticles.

注意到种硅基微粒是化学工程师兼材料科学家耶德利·科拉雷斯-包雷尼亚。

For example, during a meal, fatty acids get packaged into balls of fat called chylomicrons by the small intestine.

比如进餐时脂肪酸被小肠包裹成叫作乳糜微粒脂肪球。

Well, short-term exposure to the particulates from the forest fires is manageable, doctors tell me.

医生告诉我，短期接触森林大火产生微粒是可控。

Exhaust increases the number of tiny particles in the air, on which water vapor condenses to form cloud droplets.

废气空气中微粒数量增加，而水蒸气则在微粒上凝结成云滴。

In the end it's a good reminder of how everything boils down to particles either reacting or not reacting.

最后，也是一个很醒，所有东西，无论发不发生反应，是怎样烧成微粒。

Microscopic particles in the air can affect breathing and cause other problems.

空气中微粒可影响呼吸，并引发其他问题。

And those massive amounts of particles can cause clouds to form.

排出巨量微粒便会形成云朵。

You can feel the little bits of food inside.

你会感到里面食物微粒。

The tiny dust particles drill into the child's lungs.

沙尘微粒进入了珍妮肺部。

And smaller debris, when ingested by young fish, can interfere with growth and development.

更小微粒会聚于小鱼腹中，影响生长和发育。

Trillions of these subatomic particles pass clean through your body every second.

每秒有上万亿颗种亚原子微粒穿过你身体。

The machine gives the molecules on the swab an electric charge, turning them into ions.

ETD会给棉签上微粒带上电荷，它们变成离子。

But how they got airborne was a mystery.

但它们如何升空成为大气中微粒仍是一个未解之谜。

Tiny as they may be, the particles may actually affect the climate.

尽管些土壤微粒极其细微，但也会对气候造成影响。

And so they create what we call microplastics.

然后，他们创造了我们所谓塑料微粒。

They're covered in microscopic particles of shrapnel known as " war sand" .

它们被称为“战争沙子”弹片微粒覆盖。

Over time, it keeps breaking into smaller and smaller, eventually invisible, particles.

随着它不断分解成越来越小部分，最终会分解成看不见微粒。
