查询词典 sediments

This paper discusses the research carried out on the Lake Sugan, in the northern margin of Chaidam Basin. The climate and environmental changes in Lake Sugan drainage area over the past 2670 years were studied using the varve dating of the well preserved lamination sediments in core SG03I taken from the center of Lake Sugan, the study of varve formation in modern lake system and modern process study of carbonate and oxygen isotopes of the water within the drainage area, and according to the main index of the stable isotopes of carbonate sediments synthesized other index analysis.

本文以柴达木盆地北缘苏干湖为研究对象，通过对湖泊中心位置SG03I孔保存完好的纹泥沉积物岩芯进行年代学研究，对湖泊现代沉积过程及碳酸盐、流域水体同位素进行现代过程研究，以沉积碳酸盐稳定同位素指标为主，结合其它代用指标的综合分析，探讨苏干湖流域近2670年来的气候与环境变化，综合区域其它记录对苏干湖流域晚全新世气候变化的驱动机制进行探讨，获得如下认识：1、柴达木盆地北缘苏干湖若干钻孔岩芯发现，水深大于3.0m的沉积物均具有裸眼可分辩的由深色层和浅色层组成的纹层层理。

在增生楔部位，地层深部的流体，在挤压构造应力及浮力的作用下，沿断层及地层孔隙运移至海底浅层，形成水合物。

The allochthonous deposition mainly includes the gravity current settled sediments and the tractive current settled sediments. The autochthonous mainly includes the argillaceous deposit.

深水异地沉积主要包括重力流沉积和深水牵引流沉积两大类；深水原地沉积主要包括深水泥页岩沉积。

In order to provide some scientific data for judging biological toxicity and bioavailability caused by heavy metals in sediments in Guilin, China, for the first time, the authors sampled sediments in different water areas in Guilin, and determined AVS by P-Amino dimethyl aniline dihydro chloride photometry through a set of acidification-ventilation-absorption AVS reaction unit, determined copper, lead, zinc, cadmium and nickel with tomic absorption spectrophotometry, mercury and arsenium with atomic fluorescence, and cipangopaludina cathayensis was selected as the tested species for bioavailability experiment.

首次以桂林水系沉积物为研究对象，通过酸化－吹气－吸收装置，用对氨基二甲基苯胺光度法测定沉积物中AVS含量，用原子吸收分光光度法测定SEM和间隙水中Cu、Pb、Zn、Cd、Ni含量，用原子荧光法测定Hg、As含量。

The unique geographic position of shelf and marginal sea causes the material supply of seafloor sediments plenteous and the material sources of them diverse. As terrigenous materials being input into the sea continually and a great deal of authigenous minerals coming into being, the sediments can be used to study the change of sea level and the meterail and energy exchange between the sea and the land.

陆架和边缘海独特的地理位置决定了海底沉积物物源的充足与多样性，陆源物质源源不断地通过河流输入到海洋中，同时大量的自生矿物在海洋中生成，因此研究陆架和边缘海海底沉积物，可以为研究海平面变化、海陆之间物质和能量的交换等作用提供信息。

On an average, 1.1±0.3 and 0.4±0.1 rotifers were hatched from per milliliter sediments of the big and the small basins, respectively. The rotifer species, which was hatched at one incubation pattern from the resting eggs in sediments of both the two basins of the lake and whose density was higher than 20ind/200mL, included Proalides tentaculates , Anuraeopsis fissa , Keratella cochlearis , Brachionus diversicornis , Filinia brachiata and B .
