分析了川气东送管道工程建设过程中水土流失的特点,对工程区地形地貌进行了区域划分。针对不同防治分区采取相应的防治措施即采用分层开挖、设排水沟、护坡、种树、修建拦渣墙等方式防治水土流失。同时坚持水土保持三同时制度,有效减少因本工程建设所引起的水土流失。     

企业环境等级评价制度中的多方博弈辨析

企业环境等级评价制度将公众第三方引入环境管理体系,着重分析三方在管理中的各自作用,以及如何实现利益的最大化。公众的参与是核心,政府引导是保证企业环境等级评价制度顺利和健康实施的基础,而企业可以通过环境等级评价提高企业环境信息的透明度,并进一步利用市场增大企业的利益。     

废旧电路板的解离特性分析

废旧电路板的回收方法依赖于电路板的性质,因此从定性和定量的角度确定废旧电路板上各种物质的组成和含量,对处理技术的选择非常重要。本论文主要针对目前数量最多的废旧电路板（PCB）,利用选矿技术的分离方法进行废旧电路板的解离特性研究。即破碎后的物料首先通过筛分试验确定物料的粒级组成;通过小浮沉试验确定每个粒级的金属和非金属含量。为后续分选作业的可行性提供依据。     

太浦河饮用水源地取水方式研究

太浦河是上海市青浦区第二自来水厂的水源地。自来水厂从河道直接取水,但河水部分水质未达水源地水质标准,不但加重了处理成本,也导致供水水质不能得到保证。傍河布井取水方式能自然净化水质,特别是能去除某些传统自来水厂直接净化河水不能去除的污染物质。通过分析太浦河地区水文地质及水质水量等,探讨了该研究区傍河布井取水的主要技术条件。结果显示在太浦河傍河布井取水,可获得比直接河道取水更为优良的水质,水量充足,且取水工程经济可行,有很好的开发利用前景。     

Trans-ocean wireless transfer of electricity from continent to continent

The author offers collections from his previous research of the revolutionary new ideas: wireless transfer of electric energy to a long distance – from one continent to another continent through the Earth's ionosphere and the storage of the electric energy in the ionosphere. Earlier he also suggested the use of electronic tubes as the method for transportation of electricity into outer space and the 100-km electrostatic space towers for connection to the Earth's ionosphere. Earlier a connection to the Earth's ionosphere using 100-km solid or inflatable towers was suggested. however, the technology faces difficulties. In this work, connection to the Earth's ionosphere by thin plastic tubes supported in the atmosphere by electron gas and electrostatic force is researched. Building this system is cheap and easy using the current technology. The computation allows estimating the possibility of the suggested method.     

Relations between Environmental Right for Citizens and the Right to Use Environmental Resources owned by Company and Enterprise

Abstract

From angles of administrative law and private law, the article analyzes relations between environmental right for citizens and the right to use environmental resources owned by company and enterprise and points out three principles to balancing two relations: A principle of equal protection, a principle that general interest is superior to special interest as well as taking an account for special interest, in specific circumstances, for example, in the circumstance that clashes between environmental and economic interests can not be avoided, policy makers can put an emphasis on more important social interest according after considering weight of each interest. Finally, the article reaches a conclusion that China should establish system of environmental right for citizens from legislative and administrative levels so that a harmonious society can be constructed with guarantee.     

Strategic Study on Integration of Port and City Development in Rizhao

Abstract

Agglomeration of the Yangtze Delta (UAYD), one of the most developed regions of China, has witnessed an increasing prevalence in building ecological cities when the ecological cities are pursued by many modern cities, and great achievements have been made in this regard. It is inevitable, however, that certain problems exist during the construction of ecological city, which include but not limited to non-harmonious development of urban complex ecosystem, and the difficulty in quantifying eco-city construction or incomplete quantification in assessing the construction of present and future eco-city. Based on the analysis on social-economic conditions and regional conditions of the UAYD, this paper attempts to set up an index system of eco-cities combining with local characteristics, and to adopt the indices of eco-city, urban harmony, and eco-city colligate to evaluate the ecological level, urban harmonious development and eco-city construction of cities within the UAYD. Results indicate that among 15 cities in UAYD, Suzhou City ranks the highest in terms of eco-city construction, whereas Nantong ranks relatively lower; sustainable eco-city construction is possible only when cities are developed in every respect of harmony.     

Optimization of the recovery of plastics for recycling by density media separation cyclones

Material recovery processes are presented as the optimum option for recycling plastic wastes as a means of recovering hydrocarbon resources. There exist a large variety of automated material recovery processes for recycling of such wastes but each with significant limitations. Of these, the separation based on differences in densities is advocated as the optimum process either for producing recycled products or preparing wastes for subsequent recovery processing.Density separation processes based on cyclone type density media separation (DMS) is presented as an important, potential method for increasing plastics recycling process capacities. It is demonstrated to have the capacity to separate a significantly larger range of particle sizes than those presently processed industrially. The mathematical relationship for the prediction of quality of typical LARCODEMS type density media separations by particle size and density as expressed by the Ecart Probable is presented.A proposed device configuration is presented for density media separation to optimize the recovery and purity of both density fractions produced. It is also suggested that to be economically viable, a large scale of operation is required for industrial plastics recycling operations recovering and producing a number of different plastics with a purity to be used as a substitute for virgin material.     

环境因素对供应链中生产者食品安全行为的影响机制仿真分析

通过食品安全环境因素的改善和规范,来提高食品安全效果是具有现实意义的。本文归纳了影响食品安全的环境因素,特别是影响生产者食品安全行为的环境因素;环境因素对供应链食品安全的影响主要体现在生产者食品安全行为的选择上,为此,设计了环境因素对供应链生产者食品安全行为影响机制;为了分析环境因素对供应链中生产者食品安全的影响,从生产者食品安全行为的影响机制中选取了消费者食品安全意愿、生产者市场占有率、罚款金额等环境因素,以生鲜蔬果供应链中覆盖流通领域的那个部分提出了生产者食品安全行为选择策略的仿真模型,使用Netlogo软件进行了多主体仿真。通过仿真发现,食品监管的手法还宜细化,提升技术因素可以有效改善中国的食品安全水平。
