查询词典 ocean floor

IN THE 1960 s and1970 s, the idea of mining the ocean floor was all the rage .

在1960年代和70年代，海底采矿的想法风行一时。

According to the geochemical data, the formation of mantle peridotite might be: during the spreading of ocean floor, the MOR mantle underwent variable degrees of partial melting and formed the depleted mantle peridotite with podiform chromitite; during the spreading of ocean basin, intra-ocean subduction happened, REE and LILE rich fluids containing water derived from the subduction slab migrated upwards and metasomatism happened to peridotite relic.

康金拉矿区的地幔橄榄岩的地球化学特征反映了其形成过程的复杂性，表现为：洋底扩张期间，扩张脊下的MOR型地幔的经历了不同程度的部分熔融，形成了亏损地幔橄榄岩，该地幔橄榄岩中赋存了来自深部的豆荚状铬铁矿。

Then on the basis of study results about regional geology, ophiolite,structure,and seismic depth-sounding in the Qinghai-Tibet plateau and its adjacent areas, this paper promotes a new model to interpret tectonics.This new model thinks that in this large area there was not simple B-type subduction which is accompanied with ocean-floor spreading at mid-ocean ridges to form ocean basins appearing as new oceans and new ocean plates,but intercontinental seas due to ocean-floor spreading,obduction of ophiolite tectonic slice as oceanic crust slabs and complex A-type subduction of continental lithosphere slabs.

而后又以青藏高原及邻区为例，根据区域地质、蛇绿岩和地质构造研究的成果，特别是地震测深研究的成果，详细地论证了本区不存在有大洋中脊扩张成为大洋盆地的新大洋和大洋板块简单的B型俯冲模式，但存在有海底扩张的陆间海和海洋地壳板片的仰冲以及大陆岩石圈板片复杂的A型俯冲新模式。

Using techniques first developed for the offshore oil and gas industry, the DSDP's drill ship, the Glomar Challenger, was able to maintain a steady position on the ocean's surface and drill in very deep waters, extracting samples of sediments and rock from the ocean floor.

利用最初为海洋石油和天然气工业而开发出来的技术，DEEP的科考船&格拉玛挑战者号&能够停留在大洋表面一个稳定的位置上，对深水进行研究并提取海底沉积物和岩石的标本。

Using techniques first developed for the offshore oil and gas industry, the DSDP's drill ship, the Glomar Challenger, was able to maintain a steady position on the ocean's surface and drill in very deep waters, extracting samples of sediments and rock from the ocean floor.

developed 过去分词作后置定语：这里强调一句，如果是现在分词作后置定语，因为现在分词不可能直接跟在名词后面作谓语动词吧，除非有be动词一起表示进行时。而过去分词，如果它的过去式和过去分词形式不同，也好判断。困难主要出现在过

The Glomar Challenger定位到原文第二段第二句Using techniques first developed for the offshore oil and gas industry,the DSDP's drill ship,the Glomar Challenger,was able to maintain a steady position on the ocean's surface and drill in very deep waters extracting samples of sediments and rock from the ocean floor.

推理判断题[考频：66]。原文第二段讲述了对海底进行第一次探索的情况。对海底首次进行探索始于 1968年的深海钻井工程，而在这一工程中发挥了主要作用的正是Glomar Challenger，它能在海平面上保持稳定并且能够钻入深水中，从而抽取样本。故D正确。

Jets of hot water spewing up from the ocean floor have been discovered in a far-northern zone of the Arctic Ocean, scientists announced Monday.

科学家5日宣布，在北冰洋极北地区海域发现海底喷涌出热喷泉。

Treasure on the ocean floor TODAY, deep-ocean mining is done only by the oil and gas industry.

今天，深海采矿只是在石油和天然气工业领域得以实现。
