The interplay between the two leads to the formations of fluid outer core, basalt magmas, oceanic crust, and differential rotation between the inner core and mantle.
这两者之间的相互作用导致了流体外核的形成、玄武岩浆的产生、洋壳的形成、以及内核和地幔之间的差异旋转运动。
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。
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。
