地质学

It is verified that the traditional method is hard to achieve the success to reveal the weak ore-bearing rocks.

其中岩性信息的分离、提取，一直是遥感地质学的前沿目标。

Determination of depth of granitic plutons was helpful for understanding of uplift of terranes and deep tectonism.

同时，构造地质学和大地构造学自身的研究也将不断拓宽研究领域①，如：1不断拓宽研究的时空尺度，深入了解地球早期构造作用和大陆地壳深部构造作用；2精确确定变形特征，特别是流变学特征，估算应变强度和流变学参数；3精细测定变形的时代，特别是早期变形的时间；4深入分析构造发生的动力源问题。

Granitic plutons with different ages and deformation degrees could be used as good timing markers to constrain timing of deformation, particularly to the timing of early deformation by zircon U-Pb dating.

21世纪，地质学的发展及地球系统科学研究的兴起必将对各个学科提出更高要求，特别是在有关边缘学科和交叉领域方面。

From the shore line, out to a distance which may be anywhere from a few miles to a few hundred miles, runs the gentle slope of the continental shelf, geologically part of the continents.

从海岸线向大海延伸几英里到几百英里的区域是大陆架慢坡，从地质学上说，它是大陆的一部分。大陆和海洋的真正分界线是在陡坡脚。

Strontium isotope stratigraphy relies on the fundamental principle that the marine strontium is isotopically homogenous world-wide at any time and the 87Sr/86Sr ratio of strontium in seawater of geological history has varied through time. By means of the 87Sr/86Sr ratio of marine carbonate which should record the original composition of sea water, we can date the marine sediments, research global events, such as history of basin subside, sea level change, orogenic events and palaeoclimate variation.

锶同位素地层学根据地质历史中的任何时间全球范围内海水的德同位素组成都是均一的、海水87Sr/86Sr比值随时间变化这一基本原理，利用代表原始海水的海相碳酸盐的87Sr/86Sr比值确定海相地层的年代，研究海平面变化、造山运动、古气候等全球事件，在地层学、沉积学、石油地质学和矿床学等领域中有着广泛的应用前景。

INTRODUCTION As a part of the research program of the Water Resources Division of the U.S. Geological Survey, a project was organized in September 1956 to study the mechanics of water and sediment movement in alluvial channels.

介绍 如美国的水资源区分的研究计画的一部份地质学的调查，一个计画在 1956 年九月被组织学习冲积的频道水和沉淀物运动的技巧。

It is designed as part of the first year course in structural geology for undergraduates at the University of Leeds.

这是为利兹大学结构地质学一年级学生提供的部分课程。

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。
