Teck Cominco also sold 1,800t of QB-R brand non-LME registered SXEW cathodes at a $47/t discount for July shipment and a further 900t for August shipment at a $63/t discount, both basis 1 month pre-payment. A tender for July shipment of 1,500t of "Grace" brand from Mantos de la Luna mine in Tocopilla attracted a discount of $28/t at the beginning of the month, while an additional 800t lot was sold at a $10/t discount late last week.

General layout: General idea should focus on protecting urban water sources, restoring riverways, wetlands and groundwater, improving the water body function, strengthening water resources allocation and water function regions management. Based on existing water project structures, the generallayout follows as that urban water sources conservation on the upriver, wetland and groundwater restoration on mid-river and coastal wetland and estuarine eco-area restoration on the downriver, achieve the target that rivers and lakes 'connection, green bank, clean water, flowing river', then form aquaticecosystem protection and guarantee system.
以保护城市水源地为重点,以修复河道湿地、地下水和改善水体功能为核心,以强化水资源配置和水功能区管理为关键,基于现有的水利工程体系,在流域上游建立以城市饮用水水源地为主体的生态保护屏障,在流域中游建设以湖泊为点、河道为线、地下水为面的水生态修复系统,在流域下游构建以滨海湿地和入海河口为中心的生态恢复区,遏制水土流失,增强水源涵养,保护水功能区,实现河、湖&连通、绿岸、清水、流水&,进而形成防控结合的水生态环境保护与修复保障体系。

In this work, nanostructure samples of La1-xCaxMnO3(x=0.2、0.3、0.4、0.5)were prepared by hydrothermal-precipitation method . The structural characterization of the powder samples were done by X-ray diffraction. XRD patterns showed that all the samples ate single perovskite-type phase withoutother impurity or secondary phase. The shape and size of samples were performed on Scanning Electron Microscopy. SEM photographs investigated that temperature of hydrothermal effects the phase of samples and alkalinity of the reaction mixture by ΔTad-T curve measurement device at low magnetic fielded
本论文采用水热共沉淀退火法制备了La1-xCaxMnO3(x=0.2、0.3、0.4、0.5)系纳米结构,用X射线衍射仪确定产物为单相钙钛矿结构,无任何杂峰及第二相;用扫描电子显微镜与透射电子显微镜分析了产物的大小和形貌,发现水热温度对产物的形成起决定作用,随着温度的升高,产物由薄膜状向丝状转变,而溶液的碱度可控制产物的形貌和大小,当碱度为6.35mol/L,水热温度为240 C时,La0.6Ca0.4MnO3的主要形貌为纳米丝并有少量纳米颗粒,纳米丝平均直径为40nm;最后测量了粉末样品在低磁场(1.4T)下的磁热效应,发现水热共沉淀退火法制备样品的最大绝热温度明显高于球磨法制备样品的最大绝热温变。
