It was formed inside a DAC at 113 gigapascals — about as much pressure as just outside the Earth's outer core.

这种物质是用DAC制造的113兆帕的压强中形成的——大致相当于外地核的压强。

And at room temperature, the researchers got the two liquids to mix when the pressure reached 2 gigapascals, or almost 20, 000 times the air pressure at sea level.

室温下，研究者将这两种液体溶合时用的是2兆帕的压强，几乎相当于海平面气压的2000倍。

According to computer models, sodium helide should be stable up to a thousand gigapascals, which is what you'd find deep inside large gas giants and stars.

根据电脑模型，氦化钠应该能在一千兆帕的压强下保持稳定，这么强的压强在大型气态巨星和恒星内部深处才能发现。

But if you somehow made it around a third of the way down, where the pressure is more than 100 gigapascals, you'd find metallic hydrogen, which continues all the way to the core.

但是如果用某种方式将压强降低至其三分之一，也就是100兆帕以上，你就会发现金属氢，这是一直存在于地核中的物质。
