  • 例句与用法
  • A large volume of electrically conducting fluid , the iron - rich liquid outer core of the earth , is the first of these conditions
    第一要件,要有大量的导电流体地球的外核为液态,且富含铁质。
  • The largest part of takes place because magnetic field lines are trapped in good electrical conductors such as the molten iron of the earth ' s outer core
    发生磁场的再生是因为磁场曲线被限制在良好的电导体内,如地球外核的熔融铁。
  • It consists of iron and nickel . the inner core is believed to be solid and the outer core is liquid . the major heat source of the core is the
    ,地核可细分为内外两层,内核相信由固体组成,外核则为液体,维持地热的能源主要来自地球内部的
  • The variation must in a swimming pool will soon diffuse throughout the pool , a concentration of magnetic field lines diffuses throughout the planet ' s outer core
    与游泳池中一滴有色的染料在池中迅速扩散的方式一样,一个浓缩的地磁场曲线的扩散遍布地球的外核。
  • Indeed , it may be that such fluctuations are simply extreme examples of the continuum of fluctuations in the dynamo processes , an el niflo in the weather of the outer core
    当然,其原因可能是如此大的波动只不过是发电机过程中波动连续体的极端例子,一个外核气候中的厄尔尼诺现象。
  • So the rare field reversals are most likely caused by larger changes in the flow in the outer core , or in the way in which the field lines are wound into the flow by diffusion
    这样,不经常发生的磁场倒转,很可能是由外核流体或磁场曲线通过扩散宛然进人流体方式发生较大的变化而引起的。
  • Earth ' s large size ( about 12 , 740 kilometers across ) ensures that this heat is lost relatively slowly , which explains why our planet still has a molten outer core and volcanic eruptions at its surface
    地球因为体积巨大(直径约1万2740公里) ,使热能损耗得相当慢,这说明了为什麽地球至今仍有著熔融的外核,而且地表还有火山喷发。
  • Fluid motions try to reverse the field on a few thousand years timescale , but the solid inner core tries to prevent reversals because the field cannot change ( diffuse ) within the inner core as quickly as in the fluid , outer core
    尽管流体运动会在几千年的时间尺度上使磁场倒转,但因为磁场的变化(扩散)在内核里不能与在外核的流体中一样快,所以固体的内核会尽力阻止倒转。
  • The rotational changes arise because of tidal forces exerted by the moon and inertial effects related to the liquid outer core sloshing around and to the cycle of evaporation , in which water at the equator gets deposited at the poles as ice that melts seasonally
    自转的改变则因为月球产生的潮汐力,以及因地球外核液体搅动和大气蒸发循环(赤道蒸发的水气于地极凝结成冰,并周期性融化)产生的惯性效应。
  • The numerical results indicate that the deformation within the solid inner core is very small . however , in the fluid outer core , the changes of the displacement with relatively low spherical harmonic degree ( n < 10 ) is very complicated via the radius , due to the resonance near the eigenfrequenies of the core long - period oscillations . while the spherical harmonic degree of the loading is larger than 10 , the deformation and the gravitational perturbation in the core are very small , and the earth ' s deformation response is dominantly represented as the radial displacement in the elastic mantle
    研究了地球在日月引潮力和表面负荷作用下的形变特征,数值计算结果表明,在固体内核中的形变很小,由于在长周期核模本征频率附近的共振,液核中低阶( n 10 )位移随半径的变化非常复杂,当负荷阶数超过10时,地核中的形变和扰动位都很小,地球的响应主要表现为弹性地幔中的径向位移,且随深度增加急剧减弱,地表负荷love数与信号频率的依赖关系很弱,给出了体潮love数计算的一种有效的近似处理方案。

The outer core of the Earth is a liquid layer about thick composed of iron and nickel which lies above the Earth's solid inner core and below its mantle. Its outer boundary lies beneath the Earth's surface.
