The formation of Earth's crust protected the inner layers of Earth from the high-energy particles in space, reducing the temperatures of the mantle and the core.
地壳的形成保护了地球的内层不受太空中高能粒子的影响，降低了地幔和地核的温度。
Our model predicted that the solid inner core should rotate slightly faster than the surface of the Earth.
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。
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.
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。
The earth is a multi-layered rotating system, which is mainly made up of aerosphere, hydrosphere, lithosphere, mantle, outer core and inner core.
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。
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.
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。
The core of the earth is made up of a liquid outer corea solid inner core.
地核是由一个液体的外核和一个固体的内核组成的。
