And in the earth, that electrically conducting fluid is liquid iron.

在地球上，这种导电流体就是液态铁。

It's mostly rock and ice, but it probably has a liquid iron core.

它大体上由岩石和冰组成，不过多半有一个液态铁核。

And by the passage of electric current the iron oxide is decomposed, and it produces liquid iron.

然后电流通过，氧化物分解并产生液态铁。

In the foundry, she saw hot liquid iron being poured to make the machines. She remembered this for years to come.

在铸造厂里，她看到灼热铁水被浇入制成机械。今后几年她都一直记得这个画面。

A new study models how a gigantic, morphing blob of liquid iron in Earth's outer core underneath the Canadian Arctic is losing its grip on the North magnetic pole.

一项新研究模拟了加拿大北极下的地球外核中一个巨大变形液态铁团如何失去对北磁极的控制。
