There's some helium and traces of heavier elements.

太阳中含有氦较重元素。

No, I do. II didn't write " superfluid helium" on this napkin for nothing.

我真想听。我特意把超流氦写在餐巾纸上可不是白费。

5 imperial gallons of the liquid helium. 5 You know how much helium that is?

英制加仑液态氮知道那是多氮气吗？

You can't sink. With all that helium in you, you're lucky you don't float away.

落不了，体内充满了氦气遇水不飘走就算走运啦。

Yeah, I listen to what you say. You're building a particle detector using superfluid helium.

当然，话我都有听。正在用超流氦打造一个粒子探测器。

Yes, helium, just like those birthday balloons.

是，就是生日派对上气球里用那种氦气。

And how, you ask, can we get more helium before we run out?

会问，在我们消耗完氦之前，我们怎样能得到更多氦呢？

They are made up of hydrogen and helium.

它们是由氢氦组成。

Sheldon, this is superfluid helium. Put this in your mouth, your tongue will freeze and break off.

谢尔顿，这是超流氦。把这个放到嘴巴里，头就会冻成碎片。

Next up, a helium filled floating mode of transportation.

接下来要介绍是一种利用氦气做能源进行漂浮飞行方法。

Hydrogen and helium are the rest of my atmosphere.

我大气层主要由氢气氦气组成。

They're mainly just hydrogen and helium.

它们主要是氢氦组成。

Helium, what's something that has helium?

氦，什么东西有氦？

It's just a giant ball of hydrogen and helium gas.

它只是一个巨大氢气氦气球。

We need to calculate all the Euler angles that would cause the sun to hit the liquid helium.

我们需要算出所有欧拉角避免太阳直射到液态氦。

However, the largest mass leaks are associated with hydrogen and helium.

然而，最大质减与氢氦有关。

The Sun gets hotter because it's burning hydrogen into helium.

太阳会变得越来越热，是因为她由燃烧氢转为烧氦。

It ended when the first stars started fusing hydrogen into helium.

当第一批恒星将氢融合为氦时，黑暗时代结束了。

Jupiter's atmosphere is made up mostly of hydrogen and helium.

木星大气层主要由氢氦组成。

So we're simultaneously heating it, and then we also have the helium to make sure it doesn't overheat.

所以我们会同时加热，然后我们还会使用氦气来确保它不会过热。
