    基于TiO2半导体特殊的光电化学性能,其有望成为绿色、环保的新型金属防腐技术中最为重要的光阳极材料。但是,TiO2存在可见光利用率低、光量子效率不高等限制其实际应用的问题。此外,由于传统混合方式在快速沉淀体系中难以有效调控均相化学过程,导致碱性液相环境制备有序TiO2薄膜至今仍无法实现。基于上述考虑,本论文提出使用微混合设备辅助在碱性液相环境下制备出形貌可控的TiO2薄膜光阳极,并通过沉淀剂对产物进行选择性原位掺杂改性。通过数值模拟及实验测试深入研究了制备条件和掺杂对TiO2薄膜光阳极光电化学性能的影响。本论文的主要研究内容和结果如下: 1、基于自行设计并制造的多孔分散微结构混合器,对液-液...TiO2 semiconductor is expected as the most important photoanode material applied for the novel green and environmental friendly metal anticorrosion technology, because of its unique photoelectrochemical properties.

    关于我国建立行政公益诉讼制度的探讨

    Get PDF
    我国现行的行政诉讼法只设立了保护“公民、法人和其他组织”合法权益的诉讼,将违法行政行为侵害公共利益这种情形排除在行政诉讼之外,从而使被行政权侵害的公共利益难以得到有效的司法救济。但公共利益是一种客观存在,对它的救济同样也不应排除在司法的视野之外,法律对公共利益和个体利益的同等保护是法治原则的基本要求。因此笔者提出了在我国建立行政公益诉讼制度,从法律上设定一个代表公共利益的主体启动诉讼程序,从而保证在公共利益受到行政权侵害时能够将争议付诸司法程序。对于建立什么样的行政公益诉讼制度,学界提出了两种观点,一种主张扩大原告资格,任何公民都可就此提出诉讼;一种主张设定特定的公共利益代表主体向法院提出诉讼...学位:管理学硕士院系专业:法学院政治学与行政学系_行政管理学号:20000600

    环境规划中的公众参与在世界各国和国际社会得到普遍推行,它可以使公众了解规划项目以及由此可能引起的重大的、潜在的环境问题,增强规划的合理性和社会可接受性,从而有利于最大限度地发挥规划的综合和长远效益。我国环境规划中的公众参与起步稍晚。发展到今天,虽取得了一定的进展,但还存在参与意识淡薄、深度不够和参与效果欠佳等问题,影响了公众参与的有效性,导致环境规划的有效性也减低,不利于环境保护的长远发展。在发展我国的公众参与时,应结合本国具体情况,不应完全模仿国外的模式,应在不断吸收、去粗取精、总结经验教训的基础上来发展适合我国国情的公众参与。本论文从提高环境规划中公众参与有效性的角度着手,概述了公众参与的...The Public Participation system in environmental planning is widely carried outin the world, which is able to make the public know the plan and the importantpotential environmental problems resulting from the projects.

    核级UPS是核电站的重要设备之一,对核电厂的安全稳定运行起重要作用。为保证设备质量和可靠性,核级UPS需要进行抗震强度分析确保其通过抗震试验鉴定,使其满足当电厂实际发生地震的烈度在鉴定试验抗震响应谱的包络范围内设备能够安全运行。使用HyperWorks软件对核级UPS进行结构抗震强度分析,以确保其结构设计满足核级设备的抗震要求。The nuclear-class( 1E class) UPS,as the significant power supply in nuclear power plant,plays a dual role in protecting and controlling the power supply,which is vital to the safe and stable operation of nuclear power plants. In order to improve reliability of power supply,UPS of nuclear power plant requires enough anti-earthquake ability,which means that the mechanical properties of the UPS during the process of designing and producing should be fully considered. What 's more,for ensuring the safe operation of equipment,it is indispensable for effective structural strength analysis and anti-earthquake analysis to make UPS cover earthquake response spectrum of given. In this paper,we innovatively use Hyper Works software into structural anti-earthquake intensity analysis of nuclear-grade UPS,to ensure the structure design satisfies the demands of nuclear-class devices

    根据古代文献关于"饮病"和现代医学关于高血压病的认识,"饮病"与高血压病无论从临床表现还是从发病机制上都有着密切的相关性。近年来,"痰饮"成为高血压病发病的重要病因之一,并贯穿于高血压病发病的始终。五苓散、苓桂术甘汤等具有"化饮"功效的方剂在治疗高血压病的临床实践中已取得较好疗效,但始终缺乏从饮论治高血压病的辨治纲要。因此,将"饮邪"引入高血压病的致病因素之中,对其做系统性、理论性的探讨,并总结出一套治则治法,对指导临床实践具有一定的帮助。According to the ancient literature on the"retained fluid disease"and modern medicine on the understanding of hypertension,"retained fluid disease"and hypertension disease from clinical manifestations or from the pathogenesis are closely related. In recent years,"phlegm"has become one of the important causes of hypertension,and always runs through the occurrence of hypertension. Wuling Powder and Linggui Zhugan Decoction have"dispersing retained fluid"effect of the prescription in the treatment of hypertension in clinical practice to obtain good curative effect,but always a lack of debate on the treatment of hypertension from the theory of"retained fluid disease"treatment program. Therefore,put the"drink evil"into the category of hypertension disease,on the system,theoretical study,and sums up the prevention and treatment,to guide the clinical practice has certain help.2013~2015福建省中医药科研项目计划(课题名称:五苓散健脾-利水-温阳通脉多靶点途径调控高血压大鼠RAAS表达的机制研究)(编号:wzln201309);; 2013年夏门市科技局高校、科研院所科技创新项目(课题名称:柴苓降压剂的开发研究)(编号:3502Z20134052
