High concentrations of particulate heavy metals occurred at the beginning of the food-tide, around the slack water and latter of the ebb tide over the course of five tidal cycles, which was mainly caused by the hydrodynamic conditions.

这种变化主要与水动力条件有关，当水体流速增大时，从底部沉积物再悬浮起来的颗粒态重金属对水体中的永久性悬浮颗粒起了很大的稀释效应。

The source of slack deposits is the loess of the upper reach where the soil erosion is very heavy, while the source of sand is the airslaked rocks of mountainous area in the upper reach. 3. There were several "interbedded slack deposit-aeolian fine sand layers" in both LHT and YWC profiles, the silt layers are slack water deposits and the aeolian fine sand layers were carried by the NE direct wind.

在LHT、YWC和YYC剖面中，磁化率均呈现出平流沉积层中偏低，而在风吹沙和中、粗沙层中偏高的特点，其原因是平流沉积层的物质来源多为上游黄土区的土壤侵蚀和水土流失带来的土壤，而沙层的物源则是上游基岩山区的岩石经风化、搬运而来。

Character: White or almost white crystalline powder, smell-less;Assay:≥98.5%;Solubility:Soluble in water, Slightly soluble in acetone and ethanol;IR:Complies with the working standard;Chemical identification:Red;Na Salt indentification:Complies with the standard;Relative substance:Complies with the working standard;pH:8.0-9.5;Loss on drying:≤0.5%; Heavy metal:≤ 20ppm

特征及特性：应为白色或类白色结晶性粉末；无臭，无味；含奥扎格雷钠(C13H11N2NaO2)≥98.5%；在水中溶解，在乙醇和丙酮中微溶；IR图谱与对照品一致；化学鉴别应显红色；溶液主斑点与对照品溶液主斑点的位置相同；钠盐鉴别符合规定；有关物质鉴别符合规定；pH：8.0～9.5；；干燥失重≤0.5%；重金属≤20ppm

In order to establish relative analysis methods and find out transfer rules and vertical distribution characteristics of heavy metals in sediments of Poyang lake,column form sampler designed by us was used in the experiments,the sediments samples from Wucheng section of the Ganjiang River in Poyang lake area were collected using adjacent water vertical spile method.

为建立鄱阳湖水域沉积物中重金属的相关研究方法，了解重金属污染物的迁移规律，并探讨底泥中重金属的垂直分布特征，采用底质柱状采样器通过临水垂直插管法采集鄱阳湖流域赣江吴城段的底质样品，利用微波消解—AS-990型原子吸收分析体系对柱状样中不同深度的样品进行重金属Cu含量的测定。

" This is due to restricted irrigation water coming mostly from South Ossetia and the fact that during the hostilities heavy military equipment passed through many fields damaging the crops ," said Spindler .

这是因为有限的灌溉用水多半来自南奥塞梯，而且在冲突期间重型军用设备碾过许多农田，毁坏了庄稼。

In recent years, the forever-lasting Taiwan and green architecture have become a major topic in our country. In order to resolve the runoff of rainwater resource, to prevent the spoliation of ecology and to reduce the effect of heat island, to search for the suitable mix design of the pervious concrete for Taiwan is not a small issue. Pervious concrete pavement is air permeable and water permeable, the soil underneath can be kept wet and rainwater can quickly filter into ground, so the groundwater resources can renew in time. It improves the environment of road pavement and also possesses many other advantages that improve city environment at drainage, sound absorption and skid resistance, and is suitable for the rainy and humid environment in Taiwan area. However, its high air voids results in low strength, the surface layer of highway pavement was seldom used pervious concrete due to heavy traffic loading.

近年来国内以打造永续台湾与绿建筑为未来努力的方向，为解决雨水资源流失、环境生态破坏及热岛效应扩张，研发本土透水混凝土实有其重要性，透水混凝土铺面可以使空气与水自由地有效的渗入，地下土壤可保持湿润，雨水也能够快速渗入地面至地下水，地下水资源或水位能即时更新，它改善道路铺面的环境，其它的优点尚包括具有良好排水、噪音吸附与车辆抗滑能力，适合铺设於台湾多雨多湿之环境，由於透水混凝土孔隙率较高，其强度低於一般混凝土，应用於重交通量公路面层因此受到局限。

This system adopts the methods of high voltage control cabinet and starting cabinet using water resistance so that starting with heavy load of main motor and running safty is ensured.

国产水泥磨电控系统目前大多采用自成一体的单机系统，但随着多数大型水泥厂的技术改造，越来越多的水泥厂已采用了全厂集散型控制系统[1]。

"Contain enlarge of station of sewage disposal of heavy metal ion to be able to transform a project " construction dimensions is treat industrial foul water everyday 8000 stere, always invest 93.08 million yuan.

"含重金属离子污水处理(通过物化方法去除水中一些物质的过程)站扩能改造工程"建设规模为每天处理工业污水8000立方米，总投资9308万元。

In recent years, with the rapid development of social economy, plenty of industrial wastes and sanitary sewages were poured into natural water, of which subsistent heavy metal ions can affect human health seriously.

中文摘要：近年来，随着经济社会的快速发展，大量工业废水和生活污水排入天然水体，尤其是废水中的重金属离子严重影响人类的健康。
