To counteract this oxygen would have to be diluted with non reactive gas.

为了制造这种情况，氧气中空气比率需要性气体来降低。

Nitrogen is an inert gas, so high temperatures and pressure changes have less effect.

氮气是性气体，所以高温和压强变化不会对它产生很大影响。

But most of Earth's nitrogen exists as an inert atmospheric gas that organisms can't use.

但地球上绝大多数氮气都是以一种生物体无法使性气体形式存在。

A noble gas is an example of that.

性气体就是一个例子。

Most of it, about 92%, is hydrogen. A further 8% is helium, which is chemically inert.

大部分（约92%）气体是氢，另外8%是性气体氦。

To avoid inert gas narcosis, many divers fill their tanks with Heliox, which combines 21% oxygen with 79% helium.

为了避免性气体麻醉病症，许多潜水员会在水箱中注入一种氦氧混合剂，这可以将21%氧气和79%氦气混合在一起。

They examined fluids seeping out of fractures in a mine and found particular isotopes of the noble gas xenon.

他们查看从矿井裂缝中渗体，从中发现了性气体氙特殊同位素。

He says saturation diving technology enables human beings to withstand high water pressure by saturating human tissue with inert gas.

他表示，“饱和潜水”技术，让潜水员体内各组织体中所溶解性气体达到完全饱和程度，来适应高压环境。

And so let's throw a noble gases up here.

因此我们把性气体放在这里。

Halogens, Noble gases, lanthanides or rare earth elements.

卤素、性气体、镧系元素或稀土元素。

Helium, an ultra-stable, very low-energy noble gas, has 2.

氦气是一种超稳定、能量极低性气体， 具有 2.

Yep, it's unreactive, it's an inert gas.

没错，它不活泼，是一种性气体。

They could start pretending like they're a noble gas.

他们可以开始装作自己是性气体。

Everyone wants to look like a noble gas.

每个人都想看起来像性气体。

So what it is, it's an inert gas.

所以它是一种性气体。

And if it weren't for them we'd never have noble gases in a liquid phase.

如果不是他们, 我们永远不会有相中性气体。

(5) One hour before inert gas system operation is required (for tanker)?

(5) 性气体系统需要运行前一小时（货船）？

These could be a liquid noble gas, germanium and silicon crystals, a refrigerant, or other materials.

这些可能是态性气体、锗和硅晶体、制冷剂或其他材料。

And so this graph, what we're looking at are a bunch of noble gases.

所以这张图, 我们看到是一堆性气体。

Group 18 solids meanwhile are the solid phase materials of the noble gases Group 18 on the periodic table.

第18族固体是周期表中第18族性气体固态物质。
