查询词典 sediment-covered

Concentrations of heavy metals in the suspended matter and sediment are not obviously affected by elutriation of stream and dilution of tributary stream. This feacture does not change even in the distant reach downstream. Therefore, the suspended matter and sediment are the potential source of heavy metal contamination to the waters for industry and agriculture use.

河流的地质、水文特征决定了河流悬浮物和沉积物成为河流中重金属搬运迁移的主要载体，在几十公里的下游水域中悬浮物和沉积物中重金属含量没有受到其它支流清澈水体的稀释，成为下游工、农业用水的潜在污染源。

Within the embayment, the sediment accumulation rates are relatively low, with an order of magnitude of 〓, due to a small sediment supply.

多种研究方法表明，胶州湾沉积速率较小，其量级为〓；这主要与胶州湾沉积物来源较少有关。

Aimming at the problem of the erosion of parts of seacoast after the variation of flow and sediment in the Yellow River estuary,we research on the relationship between the epeirogenesis of seacoast and the variation of flow and sediment using the methods of field data analyses and theoretical study.

采用实测资料分析和理论探讨的方法，研究了黄河口海岸造陆与水沙过程变异的关系。

Based on calculation of silt-deposit sediment, the mode of sediment budget of Changjiang Estuary is established for the first time.

在冲淤量定量计算的基础上，首次构建了较精确的长江口泥沙收支平衡模式。

Based on the theory of tidal flow and sediment motion, a 2-D depth-integrated mathematical model for the Jiaojiang Estuary is developed by using explicit scheme of finite difference on the triangle elements. The results show that the rotary currents occurring in this area can be simply and effectively simulated by the model. Meanwhile, the suspended sediment concentration simulated is in agreement with the field data.

本文根据椒江口实测水文地形资料，从平面二维水流泥沙基本方程和基本理论出发，采用三角单元有限差分法对水流泥沙方程显示求解，对椒江口潮流泥沙进行了数值模拟，模型简单实用，较好地再现了具有旋转潮波性质的椒江河口水流运动特征，含沙量场也得到了基本正确的反映。

At the confluence zone, due to the jacking of current from main stream and tributary stream, the mixing and turbulence of current is so strong and the loss of energy is so large that the balance of water and sediment is broken which could causes sediment particle and coarse grain to deposit and forms shallow shoal at river mouth or eyot.

天然河流中存在着大量的干、支流交汇的河段，在干支流相汇处，由于干、支流两股水流相互顶托，交汇区内水流紊动掺混作用强烈，能量损失很大，干、支河流原有的水沙平衡状态被打破，可能导致泥沙颗粒、尤其是粗颗粒卵石在汇合口处大量淤积，形成河口浅滩或江心滩。

Also different seismic facies and sediment units have been recognized with the establishment of the of sediment system model.

识别了不同类型的地震相；识别了不同类型的沉积相单元；建立了沉积体系模型。

The common assumption that the ratio between particulate organic carbon and particulate 234Th obtained from shallow sediment traps and filterable particles are representative of the ratio in the total particle settling flux should be treated with caution in view of well-known biases associated with tethered shallow sediment traps and the decoupling between size and settling velocity of many natural particle regimes....

在微粒有机碳和从浅薄沉淀物和可过滤颗粒中得？？？？？的第234种元素的比例是所有沉淀物熔化比例的典型代表。从众所周知的关于浅薄沉淀物的范围以及在许多天然颗粒体的大小和沉淀速率这个角度来看，这种通常的假设应谨慎对待。。。

On the basis of previous study on deep channel, the South Branch,Xinqiao Channel,Nanxiaohong and Main Channel of Nangarg are chosen as the typical flood and ebb channels. Field data sampled in the flood season of 2001 and the dry season of 2003 are used as the base of the analysis of hydrodynamic characteristics, such as current, sediment, dominant current and dominant sediment.

在前人对河口冲刷槽研究的基础上，选择长江口南支、新桥水道、南小泓和南港主槽作为典型涨、落潮槽研究对象，以2001年洪季和2003年枯季实测资料为根据，比较分析了长江口涨落潮槽的水流、泥沙、优势流和优势沙等动力特征，结果表明用单一因子分析河槽性质不够全面。

Basod on the field hydrologic and sediment data, the river resistance,scouring and silting behavior,flow\|sediment and tidal movment law in the estuary reach of floodway of the Ziya River has been comprehensively analyzed.

利用实测水文、泥沙资料，对子牙新河尾闾段的河道阻力、冲淤特性、河口水沙及潮汐运动规律进行了全面分析。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
