Made up of ice particles, Saturn's rings are 250,000 km across, but only 10 meters thick!

土星环由冰粒子组成，直径25万公里，但只有10米厚！

Today you learned that Saturn is a gas giant, and has a broad set of rings made of ice particles.

今天你学到了土星是一颗气体巨行星，它有由许多冰粒子组成的光环。

If you're an ice particle in the Cassini division, you orbit Saturn twice for every one time Mimas goes around.

如果你是卡西尼缝中的一颗冰粒子，土卫一每公转一圈，你就会公转两圈。

The smaller ice particles are lighter, so they're constantly traveling upwards inside the cloud and colliding with larger ice particles, thus generating electric charges.

较小的冰粒子较轻，因此它们在云中不断向上移动，并与较大的冰粒子碰撞，从而产生电荷。

Sometimes, dry ice particles or liquid propane are used.

有时，使用干冰颗粒或液态丙烷。

And this was microscopic stuff, ice particles, dust, a lot of it wasn't unlike the lint that comes out of your dryer.

这些微小的冰粒、尘土像干燥器上的棉绒。

It contains many groups of tiny ice particles called snow crystals.

它包含许多称为雪晶的微小冰粒。

It may have to do with the circulation of water droplets and ice particles within them.

这可能与其中的水滴和冰粒的循环有关。

Here, upward and downward air currents carry water droplets and ice particles, causing collisions among them.

在这里，向上和向下的气流携带着水滴和冰粒，引起它们之间的碰撞。

Just what is snow, anyway? Snow is a form of frozen water. It contains groups of ice particles called snow crystals.

究竟什么是雪？ 雪是冻结水的一种形式。 它包含称为雪晶的冰粒组。

An " icestorm" is when it seems to be raining, except that it's not rain drops, it's little, little tiny ice particles.

“冰暴” 是指似乎在下雨，只是它不是雨滴， 而是非常非常小的冰粒。

On the flipside, if those same ice particles were surrounded by cold, below freezing air all the way down, it stays frozen, and you'll need a shovel because you're going to see all snow.

另一方面，如果这些相同的冰粒被寒冷的空气包围，一直处于冰点之下，它就会保持冰冻状态，于是你就需要一把铲子，因为你会遇到降雪。

Manhattan was frozen and gray, one of those bleak days when ice particles seem to hang in the air, the chill pierces your bones, and only eyes, occasionally noses, are visible.

曼哈顿冰冷而灰暗，那是那些阴冷的日子之一， 冰粒似乎悬浮在空气中， 寒意刺骨，只能看到眼睛， 偶尔还能看到鼻子。
