There's some helium and traces of heavier elements.

太阳中含有和少量较重的元素。

Helium, what's something that has helium?

，什么东西有？

Let's go check to see if the university has any helium in reserve.

我们去查查大学里还有没有气存货吧。

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

英制加仑的液态氮你知道那是多少氮气吗？

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

当然，你的话我都有好好听。你正在用超流打造一个粒子测器。

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

你落不了，体内充满了气遇水不飘走就算你走运啦。

They are made up of hydrogen and helium.

它们是由氢和组成。

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

我真的想听。我特意把超流写在餐巾纸上可不是白费的。

Yes, helium, just like those birthday balloons.

是的，就是对上气球里用的那种气。

Helium is common in labs like this.

对于这样实验室来说，气很常用。

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

谢尔顿，这是超流。把这个放到嘴巴里，你的舌头就会冻成碎片。

Next up, a helium filled floating mode of transportation.

接下来要介绍的是一种利用气做能源进行漂浮飞行的方法。

Hydrogen and helium are the rest of my atmosphere.

我的大气层主要由氢气和气组成。

They're mainly just hydrogen and helium.

它们主要是氢和组成的。

I'd love to, but we need liquid helium and our shipment's on back order for a month.

我也想，但我们需要液，而我们订的要晚一个月才到。

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

它只是一个巨大的氢气和气的球。

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

我们需要算出所有的欧拉角避免太阳直射到液态。

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

然而，最大的质量减少与氢和有关。

Suddenly, helium is converted into carbon, releasing a lot of energy.

突然间，转化为碳，释放出大量能量。

Besides hydrogen and helium, the air there is about 2% methane.

除了氢和，其空气中还有2%的甲烷。
