" Particulate matter, " also known as particle pollution, is a complex mixture of extremely small particles and liquid droplets.

颗粒物也称颗粒物污染，是一种微小的固体和液体混合物。

The particles in the air are a mix of solid and liquid droplets that get embedded into the lungs when we breathe.

空气中的微粒是固体和液滴的混合物，当我们呼吸时，它们会被吸入肺部。

[Mike] We've found meteorites like this that contain liquid water droplets in salt.

- [迈克] 我们发现了这样的陨石，其中含有盐中的液态水滴。

You do not get liquid droplets that can  make rainbows; there's just not enough water.

您不会得到可以产生彩虹的液滴；只是没有足够的水。

OK, air pollution is a very complex mixture of solid particles, liquid droplets and gaseous chemicals.

好的，空气污染是固体颗粒、液滴和气态化学物质的非常复杂的混合物。

Clouds, essentially,   are liquid droplets or solid particles suspended in the atmosphere of a planetary body.

本质上，云是悬浮在行星体大气中的液滴或固体颗粒。

What's more, as the condensing water vapor molecules bond together into liquid droplets, they release the energy they absorbed from Earth's surface when they evaporated.

另外，当水分子彼此结合，从蒸气凝结成水滴，它们会释放从地表蒸发时所吸收的能量。

This small slice of air is composed of numerous small particles including pollen, fungal spores, and liquid droplets, alongside trace gases like methane and carbon dioxide.

空气的这一小部分包含了数种小型粒子，包括花粉、真菌孢子、液态飞沫，还有微量气体，如甲烷及二氧化碳。
