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 inner core, made of very pure, solid iron, rotates along with the outer core, dragging the Earth's magnetic field with them.
