查询词典 crust

对我国东部下第三系源岩发育的壳幔背景及空间展布、源岩发育的构造背景、沉积和盆地环境、有机质赋存状态、有机质丰度、类型及地温场特征等方面的研究表明，秦岭-大别和郯庐断裂的生成演化是区内下第三系盆地发育的主要构造控制因素，渤海湾北东向裂谷型盆地规模大、切割深，有效烃源岩最为发育；南华北近东西向-北西西向断陷型盆地规模小、切割浅，有效烃源岩相对最不发育；而立交桥型的南襄盆地有效烃源岩发育程度介于两者之间。

The current advances of the studies of geochemistry and paleoceanography of the Co rich crust are reviewed in this paper.

本文综述了近年来国内外富钴结壳地球化学与古海洋学研究的新进展。

As the extremely low growth rate and stable forming environment,Fe-Mn crust is the ideal fossil of Paleoceanography and global change.

由于铁锰结壳极低的生长速率和较稳定的形成环境，使它成为古海洋学和全球变化研究的理想&化石&。

All these characteristics suggest that the perlitic rocks might have originated from upper crust, and their pyroxene xenocrysts may be the results of assimilation and contamination of wall rocks during the migration and ascent of magma.

这些特征表明，珍珠岩原岩可能来自于上部地壳，其辉石等捕虏晶为岩浆上侵运移过程与围岩发生混染作用的结果。

The petrological and isotopic features indicate that the Lisong enclaves and hosting granite were basically crystallized at the same time, but with different crust-mantle proportions and different sources.

岩石学和同位素地球化学特征也表明，里松包体和寄主花岗岩基本同时结晶，但壳幔比例和来源有所不同。

We are engaged in producing and designing of communication apparatus and fitting, in precision machining, such as housing, panel, placode and crust of duplexer, filter, transport mixer, tower magnifier used in electric equipment and communication ; parts of SMT or vacuum equipment ; clamps .

主要从事生产、开发通讯器材及配件，精密机械加工，产品有：电子设备、通讯设备所使用的双工器、滤波器、传输混合器、塔式放大器等产品的腔体、面板、基板、罩壳类零部件、smt设备用部件、真空设备部件及工夹具等。

Combining the available regional geological and geophysical research, the petrogenesis of the magmatism was studied. As a response and absorption to the IndiaAsia collision, the northeastward flow of the asthenosphere beneath the Tibetan Plateau along the 400 km depth interface was blocked by the North China craton, and caused a systemic sequences in West Qinling Region, including the strikeslip fault systems and pullapart basins in the shallow crust and the origin of the twotype magmatism in this work in deep lithosphere. This explanation is consistent with the lithology and plumelike geochemical features of the kamafugite and potassic trachybasalt, which are significantly different from the potassic magmatism within the plateau and its adjacent regions.

结合前人对该区深部地球物理和断裂构造的研究，论证了火山岩的起源与成因，指出作为对印度-欧亚大陆强烈碰撞的吸收与调节，高原下软流圈地幔流沿400 km界面向北东方向的侧向流动以及西秦岭周边克拉通块体的阻挡，是形成西秦岭断裂系左行走滑特征和巨大拉分盆地的主要原因，也是导致西秦岭新生代两类钾质火山岩和碳酸岩起源与成因的动力学机制，较好地解释了西秦岭新生代岩浆作用起源深度大，具有地幔柱源的地球化学特征，岩石组合与地球化学有别于高原内部及其周边地区新生代钾质火山岩的原因。

There's also postglacial rebound, with the crust and mantle that were depressed by the huge ice sheets that sat on the surface during the last ice age now rebounding upward on the order of a centimeter a year.

也有冰河期的反弹，随着地壳和地幔被巨大的冰块压制着，在上一个冰河世纪的表面，现在以每年一厘米的速度向上升。

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。
