This inference is supported by high velocity, high density and high geomagnetic intensity of the crust.

这一推断得到盆地内部高磁性、高重力异常的支持，也与盆地具有较高的地壳平均速度相一致。

This field is essential to navigation, communication, geophysical exploration and many others.

地壳磁场是地磁场的重要组成部分，对导航、通信、地球物理勘探等有重要意义。

Which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc.

这些杂质通常都是由地质运动造成的，包括地壳运动，火山爆发，沉降，冰河和风化等等

The study of glacial structure will extend the topics of glaciology, and make a contribution to construct the physical and mathemtical models of deformation of rocks.

冰川是地壳上重要的地质体之一，开展冰川构造的研究不仅丰富了冰川学的研究内容，而且也开拓了构造地质学的研究领域。

Geomorhopologic landscapes in Xinjiang provided important cules for the studies of tectonics and crustal evolution, glaciology and geocryology, mountain research and desert research, and so on, it is valuable for science research and popular science education.

新疆地质地貌景观为大地构造及地壳演化研究、冰川冻土和山地研究、沙漠研究等领域科学问题的探讨提供了重要线索，具有极高的科学研究价值和科普教育价值。

The water loading was simulated based on the digital terrain model of the Three Gorges region. The vertical deformation of the Three Gorges area was calculated according to the Farrell's globosity deformation theory.

根据三峡地区的数字地形模型，模拟三峡工程3次蓄水后的水体负载，利用Farrell提出的质量负荷产生的地壳形变理论，推算3次蓄水后三峡水库库区的垂直形变。

Example It is generally accepted that the single super continent known as Pangaea indeed existed, that Pangaea subsequently broke apart into two giant pieces, Gondwanaland in the south and Laurasia in the north, and that the continents attached to the various crustal plates separated and drifted in various directions.

人们普遍接受，Pangaea 以一个特别大的陆地形式存在，后来他被分为两个大块，在南边的 Gondwanaland 和在北边的 Laurasia，他和那些在不同地壳上的大陆分开了并且向不同方向上漂移。

The LVZs in lower crust in North China Plain, Taihang Mountain and Shanxi Graben System present the clear NNE orientation. It is coincident with the orientation of the surface geological structures.

地壳下部的速度异常在华北平原地区、太行山地区和山西地堑系呈明显的北北东向分布，与区域地表的构造走向十分吻合。

During the Pliocene to early Pleistocene strong NW-SE crustal extension resulted in disintegration of the planation geomorphology and formation of a graben basin in the area.

上新世至早更新世时期，强烈的NW-SE向地壳引张导致太行山隆起南段夷平地貌的解体和地堑盆地的形成。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.

自从我们的世界一直是世界原生森林被任意剥削人。
