I've just read it's only 48 hours in the inner core or refuge, not 14 days.

我刚查到只用在隐蔽处待48小时，不是两周。

The solid inner core is about 1200 kilometers in radius, or about 10% the radius of the Earth.

这个固态内核的半径约为1200千米，大概是地球半径的10%。

At its very center is the core, which actually has two layers, the inner core and the outer core.

位于正中心的是地核，它实际上有两层，内核和外核。

President Hollande had indicated that he wanted a government of clarity. Much of his inner core stays the same.

奥朗德总统表示他希望有个明晰的政策，而核心职位很多保持不变。

In the inner core, the pressure is extremely high, and even though it's hot, iron is solid.

内核里的压强极高，因此尽管内核很热，铁元素也是固态。

A " southern" camp headed by France wants something different: " European economic government" within an inner core of euro-zone members.

以法国为首的 “南部” 阵营想法迥异，法国提倡在欧元区成员国组成的内核中设立/建立 “欧洲经济政府”。

Knowing how the inner core rotates could shed light on how these layers interact and other processes deep in the Earth.

Wow! That must be so hot! Right. Let's listen now to Simon Redfern talking about the inner core and what's happening in there.

哇！那一定特别热！让我们听西蒙·雷德芬给我们介绍一下地球内核的情况吧。

Yes. The Earth has a dense inner core surrounded by a fluid outer core. Dense, by the way, means heavy in relation to its size.

是的。我们地球稠密的内核由一个液态的外核包裹着。说明一下，Dense是指体积一定时重量大。

Scientists believe the spin of the inner core is driven by the magnetic field and balanced by the gravitational effects of the Earth`s mantle.

科学家们认为，内地核的旋转是由磁场所驱动的，并与地幔的引力作用相互平衡。

Heat, originating from the formation of our solar system, drives the rotation of liquid metal around the solid inner core.
