In the prodelta, the fine sediments spread around with the help of floatage and settle down under the force of gravity.

整体上，扇三角洲的形成是一个沉积物不断前积和垂向加积的过程，湖平面变化不同，二者作用强度不同，致使扇体形态有所差异，但扇面各部分基本维持相对固定的坡度，且沉积物的整体粒度分布趋势一致。

Studies indicate that while providing detergency at intake valves the detergents at the same time increased CCD to various extent. Comparing to regular gasoline, gasohol is more likely to form deposits at intake valves and combustion chamber and therefore needs more effective detergents.

研究发现有效的汽油清净剂在对进气阀起到清净作用的同时，均不同程度的增加了燃烧室的沉积物，这说明我国汽油清净剂的使用状况仅处于第三代汽油清净剂的发展水平上；乙醇汽油与普通汽油相比，更容易在进气阀与燃烧室内生成沉积物，因此更需要加入有效的汽油清净剂。

The formation and gathering of coal, gas, oil and uranium are always related to the given sequence position or sedimentary system. Moreover, the formation of sequences are controlled by tectonism, supply of sediments, transformation of base level and climate etc.

煤、气、油、铀形成和富集总是和特定的层序部位或者特定的沉积体系相联系，而层序的形成受控于构造作用、沉积物供应、基准面变化和气候等多个方面。

Nowadays,the properties of sediments changed by bioturbation have been concerned by International Geosphere and Biosphere Plan, especially the problems about the bioturbation and hydrodynamic coupling led to the tidal flat sediment flow differences.

如今，生物扰动对潮滩沉积物性质的改变已越来越引起国际地圈、生物圈计划的关注，尤其是生物扰动和水动力的耦合作用影响潮滩沉积物渗流差异问题。

In this paper,we briefly review the types and transformation of magnetic minerals in loess deposits,lacustrine and marine sediments and their paleoenvironmental and paleoclimatic significance.

鉴于环境磁学方法在古环境和古气候研究中的重要作用，本文对当前黄土、湖泊沉积物和海洋沉积物环境磁学研究的一些进展作简要评述。

Combined analysis of sedimentary environment,diagenesis and tectonic evolution has been applied to obtain the origin characteristics of low resistivity contrast pay.

通过建立低阻油层各种岩石物理成因与地质成因之间的关系，结合沉积环境、成岩作用、构造特征和成藏动力因素等综合分析低阻油层的发育特征，提出了5种具有典型意义的低阻油层有利勘探目标区带：（1）小规模、低幅度构造发育区，（2）天然水淹等构造运动活跃、流体非均质严重的区带，（3）岩性细、粘土矿物组合中蒙脱石含量高的区带，（4）弱水动力环境下砂泥岩薄互层发育区，（5）与火山碎屑沉积演化有关的黄铁矿等导电性矿物富集区。

Main recognition bases of the Gangdisê multiple island arc-basin system are:① tectonic pattern of collisional zones and island arc or landmass as strips alternating with blocks;②development of multiple arc volcanic-intrusive zones due to consumption of back-arc basin and arc-arc collision;③complicated paleogeographic and paleotectonic patterns shown by numerous sedimentary basin types and sedimentary facies association.

冈底斯构造带多岛弧—盆系统识别的主要依据有：①构造带中发育碰撞结合带与岛弧或陆块呈条块相间的大地构造基本格局；②发育多条由弧后盆地衰亡和弧—弧碰撞作用而形成的弧火山—侵入岩带；③众多的沉积盆地类型和沉积相组合，反映出冈底斯构造带具有复杂的古地理和古构造格局。

For the past few years, oil and gas exploration of Neogene in depression have obtained remarkable achievements and has been paid more and more attention. Therefore, the research on sequence stratigraphic framework, and tectonic control action on depositional system in syndepositional-faulted basin has great significance.

论文从层序地层格架入手，深入分析层序地层以及同沉积断裂活动对沉积体系充填的控制作用，预测储集砂体的空间分布，对陆相断陷湖盆的层序地层学研究和黄河口凹陷新近系的油气勘探具有重要的理论和生产意义。

The protolith of northern khondalite series in neighbouring region is a suite of flyschoid formation consisting of argillaceous arkose-pelitic feldspathic greywaske with intercalations of pelite, silt as well as carbonate and marl beds. They were deposited on continental margin under relative stable tectonic enviroment.

所有特征表明二者之间不存在有些研究者所认为的不整合接触关系，而是大量奥长花岗质-英云闪长质和一些中基性岩浆顺层侵入到一套沉积和火山-沉积表壳岩中，并一起经受多期复杂的变质和变形作用所成。

The thicker the DBL is, the stronger the inhibition will be. Thus, the presence of DBL in a polder reservoir can result in a delay of natural clearing process of polluted water. The effect of salt release from deposited sediments on the water quality will be a long lasting process.

另外，由于扩散边界层的存在，限制了水动力对沉积物与上覆水之间物质交换的增强作用，所以海湾水库沉积物中蓄积盐分对上覆水的影响将是长期的过程。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
