地球内核与地球自转有着密切的联系。
地球内核由外核富含铁元素的液态物质结晶而成。
The Earth's solid inner core was formed by the freezing of iron rich liquid materials making up the outer core.
地球磁场是由地球外核的熔铁围绕固体内核旋转而产生的；当铁水激增，就会发生磁暴。
The Earth's magnetic field is generated as the molten iron of the Earth's outer core revolves around its solid inner core; when surges in the molten iron occur, magnetic tempests are created.
这种（内核）影响更像是强调美学概念或是强调一种理念，即认为地球是一个发动机，能进行永不停息的变化、实现自我稳定。
The effect is more one of underlining an aesthetic, or even an ideology, of the planet as an engine of ceaseless self-stabilising change.
该星系的特点是亮白，其球形内核周围环绕着由星系螺旋结构形成的厚厚的尘埃带。 从地球上看去，星云倾斜得几乎侧立。
The galaxy's hallmark is a brilliant white, bulbous core encircled by the thick dust lanes comprising the spiral structure of the galaxy.
因为内核失去在其形成时捕捉的热能，而且是通过内核里的放射性元素产生的热能，所以地球正渐渐冷却下来。
The Earth is growing cooler as it loses the heat trapped in its creation and generated by radioactive elements within it.
我们的模型预测了固态的内核，应该比地球表面旋转得稍微快一些。
Our model predicted that the solid inner core should rotate slightly faster than the surface of the Earth.
地球是一个多圈层的旋转系统，主要由大气圈、水圈、岩石圈、地幔、外核以及内核组成。
The earth is a multi-layered rotating system, which is mainly made up of aerosphere, hydrosphere, lithosphere, mantle, outer core and inner core.
本文研究由内核超速旋转引起的地球重力场的变化。
The Earth's gravity field change caused by the inner core's super rotation is investigated.
由于内核的存在，将出现两个新的与地球自转有关的章动模式，即顺向的自由核章动(PFCN)和内核摆动(ICW)模式。
Because of the inner core of the earth, there will have two nutation modes related to the earth's rotation, i. e. a prograde free core nutation (PFCN) mode and a inner core wobble (ICW) mode.
本文的理论对进一步研究在高阶岁差章动力矩作用下的内核地球章动是非常有意义的。
This paper is very importance to more studying theory of the inner core Earth's nutation, in view of influence of higher order moment of precession-nutation to the Earth rotation.
地球的内核是—磁铁，内核的铁磁性已被观察到的地震波速度各向异性所证实。
The new theory admits the Earth's inner core to be a ferromagnet. The ferromagnetism of inner core is supported by observed anisotropic property of inner core in transmitting seismic waves.
