查询词典 geologists

After mid-century, such large syntheses, dubbed "systems," were generally repudiated, the most admired geologists being those "known for their travels, field observations, and caution against overeager generalization or systematizing."

世纪中期之后，这样的大的综合，被普遍抛弃，最受称颂的地质学家是那些&以旅行、野外考察和谨慎地避免过度普遍化和系统化而闻名的人&。

Geologists call these structures solutional caves.

地质学家叫这些结构溶洞。

Geologists call these structures solutional caves.

地质学家称这些结构solutional洞穴。

In the course of program designing, OLE mechanism and Graph for Windows have been used to generate specific geological triangular chart from computer instead of manual work in before. By using PowerBuilder 7, inquiry through a clue of combination of conditions including structural tree, strati graphic tree, well number tree and sample number tree is realized, which meets the thinking way of geologists.

在程序设计方面，针对岩石名称分类复杂、量化定名烦琐的现状，采用OLE机制和Graph for windows图形工具，对岩石含量数据进行相对数值转换，完成了平面上呈三角形排列的三个直角坐标系统的叠加，避免了人工绘制地质三角图随意性大、精确度低的问题，极大地提高了工作效率。

Since the plate tectonic theory was introduced into China in 1970's, aulacogen has been considered in the area of Helan Mountain in Ordos Basin by some geologists. It is believed that Helan Mountain, Qinling and northern Qilian area were at the stage of rifting development from Mid-Neoproterozoic to Early-Mid Cambrian, and that Qinling, northern Qilian, Helan Mountain formed a trifurcate rift valley system.

自19世纪70年代板块构造理论引入中国后，一些学者把拗拉槽一词赋予了鄂尔多斯盆地西缘贺兰山地区，并认为贺兰山、秦岭、北祁连中新元古代至早中寒武世为裂谷发育阶段，秦岭、北祁连、贺兰山构成了三叉裂谷系。

Based on the regional tectonic evolution, combined with the high precision isotopic ages from this paper and other geologists, we have some new acquaintances as follows: 1 There has no Caledonian granite belt distributed in north margin of North China Craton. So, the traditional evolving model of North China Carton, which formed on this idea and the acquaintance about the collision of North China plate and Siberian plate, must be incorrect; 2 The age date show that the earliest magmatic activity began since late-Palaeozoic Permian, which is inconsistent with the previous idea that there were Caledonian and Hercynian active continental margin in the north of North China Craton and in the south Xingkai Massif. 3 the crust and lithosphere were thickened by the subduction and collision of Siberia plate and North China plate during Late Paleozoic. The magma is formed when the crust is heated and melts caused by thickened lithosphere delamination and caused the Asthenosphere upwelling. But only a little basaltic magma erupted, most magma underplate under the bottom of the crust. Thermal energy derived from basaltic magma underplating made the middle and lower crust melt partially and the late Permian-early Triassic granites is formed in large scale.

根据区域构造演化分析，并结合本文及他人高精度同位素年龄，我们对延边花岗岩形成的大地构造环境有了新的认识：1在华北地台北缘并不存在所谓的加里东花岗岩带，因此，建立在此之上的传统的华北地台北缘演化模式及有关西伯利亚板块与华北板块的碰撞拼合的认识也必然是不正确的；2华北地台北缘和兴凯地块南缘不存在加里东期和海西期花岗岩带，表明两地块边缘最早的花岗质岩浆活动始于晚古生代的二叠纪，即不存在传统观点所认为的加里东期或海西期活动陆缘；3晚古生代由于西伯利亚板块与华北板块的俯冲碰撞，致使地壳和岩石圈增厚，导致加厚岩石圈发生拆沉作用，使得软流圈上涌，加热地壳使之熔融形成岩浆，但玄武质岩浆少量喷出地表，大部分底侵于地壳底部，形成下地壳高密度的玄武质底侵层，玄武质岩浆底侵的热能引起中下地壳广泛部分熔融，形成大面积分布的晚二叠世—早三叠世花岗岩。

But most of Iraq's geologists and engineers have left the country in the past six years, either because they could not tolerate the insecurity or because the new establishment has chased them away as Baathists formerly in thrall to Saddam Hussein.

然而，伊拉克的多数地质学家和工程师在过去六年陆续离开，可能因为他们无法容忍这里的危险局势，或者因为新政府将他们视为过去效命Saddam Hussein的复兴党人而驱逐他们。

Those geologists adventured on unknown area.

这些地质学家在不知名的地区冒险。

Besides geologists, fossilizes and geophysicists also research in petroleum.

除了地质学家外，还有古生物学家和地球物理学家也研究石油。

At its height during the last ice age, the lake may have been 900 feet (270 m) deep; prominent old shore lines, called strandlines by geologists, can be seen above Lee Vining (near the white "LV") and along volcanic hills northeast of the current lake.

在其在最后一个冰河时代的高度，湖泊可能已被900英尺（270米）深，著名老海岸线，地质学家strandlines所要求的，可以看到上面利韦宁，沿火山丘陵目前湖东北部。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
