查询词典 crust

In North Tibet, the advanced subduction plate started to break off, which resulted in mixture of the crust materials and mantle materials, and formed the source region of richening molten materials. The large-scale volcanic activity appeared in the central-north part of the plateau.

高原北部，先行俯冲板片发生断离，其地壳物质与地幔物质混合，从而形成板内富集熔体的源区，并在高原中、北部形成大规模的火山岩。

The plate previously subduced had started to break off, which resulted in its crust materials and mantle materials being mixed up, and formed the source region of richening molten materials. The large-scale magma activity appeared in the two blocks of Himalayan and Lhas-Gangdese.

先行俯冲板片发生断离，其地壳物质与地幔物质混合，从而形成板内富集熔体的源区，并在喜马拉雅—拉萨块体内形成了大规模的岩浆活动。

Firstly, geologic earthquakes - sometimes called tectonic earthquakes - are caused by the rupturing of faults in the earth's crust.

首先，地质地震-有时也叫做构造地震-是由地球的地壳层破裂造成的。

The deepest earthquakes typically occur at plate boundaries where the Earth's crust is being subducted into the Earth's mantle.

最深的地震通常发生在板块边界的地方的地壳正在俯冲到地球的地幔。

During this period, the partial melting of young and hot subducted oceanic crust at 75-85km produced he adaktitic magma.

在这期间，年轻的热的洋壳俯冲至75-85km深度左右时发生部分熔融并形成埃达克岩浆。

It crystallized from the silicate-rich supercritical fluid derived from the deeply subducted continental crust.

是大陆深俯冲过程中所形成的富硅酸盐超临界流体结晶的产物。

Our result shows that the amplitude of velocity perturbation decreases with depth, which is related to the variation in temperature. Thirdly, we use the local and regional events with focal depths from 40 to 300 km to study the subducting oceanic crust beneath Northeast Japan and Hokkaido.

接着利用3283个近震(震源深度大于40 km)分段测试了板块内的速度异常分布，结果表明速度异常随深度的增加而减小，这与地幔内的温度变化有关。

Evidently, the sulfates normally in seawater are converted to hydrogen sulfide as the water passes through the warm crust

显而易见，平常含于海水的硫酸盐在海水通过暖地壳时转变成了硫化氢。

In about 25,000,000 year, the Changbai Mountain area experienced 4 volcanic eruption activity, the basaltic magma embarked from the upper mantle, upwelled unceasingly along the earth's crust in giant crevasse, spouted the surface by the huge energy (in geology to be called crevasse type volcanic eruption).

在大约2500万年的时间里，长白山地区经历了4次火山喷发活动，玄武岩浆从上地幔出发，沿着地壳中的巨大裂隙不断上涌，以巨大的能量喷出地表（地质学上称为裂隙式火山喷发）。

And then a local extension took place in the region of intra-Eastern Tethys when the India plate drifted to the north but suffered the resistance from the Lhasa block, contemporarily, the intra-oceanic subduction are triggered, subsequently, magmas derived from a partial melting of mantle wedge which suffered from the modification by subducted continental marginal clastics and oceanic sediments upwelled along the oceanic ridges, forming several small marginal basins during 120～128 Ma, and thus lead to the so-called SSZ-type oceanic crust.

于120～128Ma，一些规模较小的边缘洋盆形成，卷入陆缘碎屑和洋壳沉积的地幔楔发生熔融产生岩浆，沿着破裂的扩张脊上涌产生了具有TNT负异常的SSZ型新洋壳，期间产生了俯冲洋壳重熔作用，标志着年轻的热的洋壳俯冲形成的埃达克岩侵入于仁布SSZ蛇绿岩地幔橄榄岩中。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
