地核

Like a simple bar magnet, this field's primary magnetic flux is directed out from the core in the Southern Hemisphere and down toward the core in the Northern Hemisphere.

地磁就如同一根普通的磁铁棒，而这个磁场的主要磁通量是在南半球由地核向上穿出，并在北半球向内进入地核。

According to the principle of quantum mechanics, exploringly presented the possible mechanism of large-scale expansion at forepart of earth, quanta earth tectonic dynamic mechanism formed from super solid state of centrosphere material, presented the integral tectonic criterion in the process of evolution of earth system considering potential of quanta, potential energy of gravitation and heat energy as a result of special state of matter of centrosphere.③Established the evolutional model of finite nonlinear expansion to of integral tectonic dynamic of earth expansion., presumed and gived the skeleton model of original forepart earth before expanding. Applying the universal large scale finite element software, for the first time considered heat power and self gravitation in the same model of tectonic dynamic model simultaneously.

较系统地讨论了地球膨胀整体构造动力的若干基本理论问题：①分析汇总了地球演化产生、积累和以各种形式损耗的总能量，根据考虑引力势能与热能的维里定理，对现时地球整体动力状态进行判断；②根据量子力学原理，探索性地提出地球大规模膨胀的可能机制——地核物质超固态形成量子简併压强产生的动力——地球量子动力，给出了考虑地核特殊物态的量子势能、引力势能和热能的地球系统演化过程中的整体动力状态判据；③建立了地球膨胀整体构造动力的非线性有限膨胀演化模型，推测给出膨胀前早期地球的轮廓性模型。

2Nd, thorough analysis: The Earth may say is an extremely marvelous thermonuclear reactor, when the earth interior pressure achieved certain critical, in the Earth material may decay the nuclear matter is called as the thermonuclear material, can have the thermonuclear reaction, thus has the huge energy, then the melted partial materials, form the rock magma are the liquid state materials, this response stratification plane is possibly many stratification planes, first possibly is located between the earth's crust and the mantle, upward next two transfers, displays for the light density material diastrophism as well as density upper mantle material phenomena and so on solidification; Under second possibly is located between the mantle and the core, the pressure is more formidable, causes not not easily to have the thermonuclear reaction thermonuclear material to have the response, forms the relative quite stable liquefied material level, simultaneously is upward next two transfers, forms the counter-flow phenomenon which the high density under mantle as well as the high density core material contact liquefies and is far away cools; These material periodicity regular movements and so on convection as well as Earth polar axis rotation are possibly the basic source powers which the terrestrial magnetic field produces.

深入剖析：地球可以说是一个非常奇妙的热核反应堆，当地球内部的压力达到一定的临界，地球物质中可衰变的核物质统称为热核物质，就会发生热核反应，从而产生巨大的能量，进而融化部分物质，形成岩浆即液态物质，这个反应层面可能是多个层面，第一层可能位于地壳与地幔之间，向上下两边对流，表现为轻密度物质的地壳运动以及中密度上地幔物质的固化等现象；第二层可能位于下地幔与地核之间，压力更为强大，引起不易发生热核反应的热核物质发生反应，形成相对比较稳定的液化物质层，同时向上下两边对流，形成中高密度的下地幔以及高密度地核物质的接触液化和远离冷却的对流现象；这些对流以及地球极轴自转等物质周期性规律性运动可能是地球磁场产生的根本源动力。

Especially the Moho discontinuity between the earth's crust and mantle, the Gutenberg discontinuity between the mantle and the core, and the gradational change between the outer and inner core.

特指地壳和地幔之间的莫霍不连续面，地幔和地核之间的古登堡不连续面，以及外地核和内地核之间的渐变面。

The centre of the earth consists of an iron core, probably with some nickel mixed in.

地心是铁芯组成，可能还混有一些镍。地球的中心是地核，地核的周围是地幔

The earth has a core and a mantle around it.

地球的中心是地核，地核的周围是地幔。

The earth have a core and a mantle around it.

地球的中心是地核，地核的周围是地幔。

With proper equations of state the relationship between the pressure and the isothermal bulk modulus is presented, which is compared with those data that come from PREM and PEM values. In order to know more about the property of matter in the inner earth's core we presented the relationship between the temperature and the volume, and the relationship between the temperature and the thermal pressure.

采用与现有地震学数据一致的地核物质状态方程，计算了300K时压强-不可压缩系数的关系图，并与地核环境下PREM、PEM模型的数据加以比较；给出了内地核环境下温度-摩尔体积、温度-热压等参数的关系曲线，研究了地核物质的热学参数；应用计算所得到的热压值，借助量子统计物理的方法，列表给出了与内地核物质量子效应有关的各项参数。

Because iron is recognized the major constitute of the Earth's core, and the Bloch-Grüneisen formula holds true in the solid-liquid mixed phase region, the electrical conductivity distribution in the Earth's core was calculated by combining with the temperature structure of the Earth's core with the PREM model. The electrical of conductivities of the Earth's core vary from 4300Ω〓cm〓 to 8400Ω〓cm〓, and increase with the pressures or depth.

既然Bloch-Grüneisen公式被证明在地核的温度、压力条件下及铁的固-液混合相区仍然有效，对于主要成分由ε-铁组成的地核，就允许用Bloch-Grüneisen公式并结合地核的温度结构以及PREM模型计算整个地核（包括液态外地核与固态内地核）的电导率分布。
