人们还依稀记得,沱江曾是四川人引以为荣的美丽之江,她淌过634公里路程,滋润三百万平方公里土地,欢快地流入长江。放眼望去,两岸青青,江水碧透,商船往来,渔舟结伴,而或夜幕降临,萤火明灭,星月当空,清风徐起,岸柳依依,情语细细。夏日里,淘气的小男孩三五成群,光着身子在江边嬉水。  相似文献

Dissolved ( < approximately 4 nm, dialysis in situ), colloidal ( < 0.45 microm filtered, minus dissolved) and particulate (total, minus < 0.45 microm filtered) concentrations of Cu, Zn, Cd, (Al) in eight (three) mining polluted rivers were determined by atomic absorption spectrometry (flame and graphite furnace). The metal size distribution in the rivers was compared to pH, Ca concentration, alkalinity, conductivity, and total organic carbon (TOC). Data plots based on the present and other studies also yielded information about the interrelations between TOC, pH and metal adsorption in rivers and lakes. Less than 10% of Cu, Zn, and Cd were sorbed on particles or colloids in two rivers with average pH at 3.1 and 5.1, whereas 46%, 21%, and 21% of Cu, Zn, and Cd, respectively, occurred in sorbed form in six pH neutral rivers. In three pH neutral rivers, on average 55% of Al was in colloidal form, whereas the dissolved and particulate fractions were 21% and 23%, respectively. Our data combined with data from similar studies support conclusions from other research suggesting that the percent fraction of metals adsorbed on particles rises steeply from almost zero to nearly 100% within a narrow and element specific pH range. Changes in TOC concentration seem capable of shifting the pH to % metal absorption curves in the order of one pH unit.  相似文献

碱-矿渣水泥缓凝物质的选择研究   总被引:3,自引:1,他引:2  
研究了氯化钡、硝酸钡、硫酸铁、铬酸钠、氯化镁、硫酸镁、硫酸铝等无机盐以及酒石酸、草酸等有机酸对碱-矿渣水泥凝结时间的影响.试验结果表明,氯化钡、硝酸钡、氯化镁、硫酸铝、酒石酸有良好的缓凝作用,硫酸铁、铬酸钠、硫酸镁、草酸不产生缓凝作用.通过强度测试发现,氯化钡、硝酸钡、氯化镁、硫酸铝、酒石酸均对碱-矿渣水泥的强度有一定的不良影响.  相似文献

海外石油项目的环境合规性管理意义重大,环境合规性管理的关键问题是识别合适的规范体系。从法学理论分析,资源国法律及其批准的国际公约、投资开发协议所要求的法律法规、金融机构的融资担保合同中所要求的法律法规、投资母国的法律规范构成了对海外石油项目的硬法约束;国际组织通过约束跨国公司行为的协定指南、企业加入的自愿性承诺、国际行业标准以及被视为最佳实践和惯例的标准导则构成了软法约束。本文结合主要国际石油公司的环境合规性实践分析,认为在实际管理中,可以根据规范来源与效力、企业追求目标等因素将上述规范区分为核心规范和其他规范,其中核心规范进一步区分为必选规范和可选规范。  相似文献

构成体系下,强调几何抽象的点、线、面、体是最基本的视觉造型元素。其中,"线"作为建筑语汇,具有造型、表意和组织等多种功能,在建筑构成中发挥着重要作用。本文用理性和抽象的方法,从构成视角出发,分析了西方现代建筑创作中关于线性要素与建筑的结构、形态、空间以及秩序等构成层面的关联性,探究其形式表现背后的构成逻辑,从而开阔建筑创作视野。  相似文献

Customers, the public generally, the water industry, its regulators and the government are aware that water can be a scarce and costly product. Resource planning and development must increasingly be viewed as a combined package of water efficiency in (a) use, (b) metering and tariff policy, (c) leakage reduction, and (d) physical schemes.
Droughts, fears over possible climate change, concerns about resources and the environment, a greater awareness of the role and costs of the water industry and statements by the Department of the Environment, the Office of Water Services, and the National Rivers Authority have added weight to this sensible shift in emphasis.
However, society needs reliable water supplies and cannot completely rely upon the uncertain impact that demand side-measures may bring about – nor, even where achieved and cost-effective, on the important savings in losses. New resource schemes can take many years to implement. Therefore, in order to ensure adequate and reliable supplies, plans for new schemes must be brought to a state of readiness, and, in many cases, implemented.  相似文献

In a time of global challenges, cities are critical not only as vehicles for progress, but also as centers of diversity and resilience. Confronted with intensifying climates, and social, ecological, and economic issues, McGregor Coxall focuses on the stories people tell in making their cities. Our projects accept and challenge these stories which underpin city-making: the engine of economic progress, the marketplace of cultural production, and the myth of our separation from “nature.” The success of contemporary city is built on a paradoxical relationship with two pressures: global development and environmental impacts. To address these crises, McGregor Coxall works at two scales, simultaneously, on all of our projects: in the large-scale realm of regional economic development and ecosystemic operations, and at the scale of the person, the street, and the neighbourhood. The systemic understanding provides the contextual basis by which projects perform, economically and environmentally, while our understanding of communities makes each project a genuine product of its time, place, and culture.  相似文献
