Review on the Theory of Machtstaat: A Study of Carl Schmitt 's State Theory

在社会极度不稳定的条件下，世界上大多数的国家依然面临着政治改革的压力，发展新的国家学说成为当前改革的需要。在中国，国家主义在这种情况之下兴起并遭到质疑。施米特的国家理论作为国家主义的崛起的理论源头之一，颇受关注。施米特国家理论到底是什么？要怎样看待施米特国家理论？本文主要通过解决这两个问题来探讨施米特的国家理论。本文研究的理论意义在于丰富对施米特的思想的研究；清晰施米特的国家理论的内容；同时厘清施米特的国家理论内容，为新的国家理论发展提供借鉴。实践意义在于帮助我们重新审视国家在现实生活中的价值与意义，从而合理界定国家的角色与地位。 本文主要考察了施米特的相关著述，总结了施米特国家理论的思想渊...Under the background of the instability of the society, the most country in the world were confronted with huge pressure from the political transition, so it is necessary to bring out a new state theory. In this case, Chinese nationalism rose and was questioned. As one of the theoretical sources of Chinese nationalism, Carl Schmitt 's state theory has been paid close attention. There were two ques...学位：法学硕士院系专业：公共事务学院_中外政治制度学号：1382013115053

Construction and immobilization of petroleum-degrading consortium

近年来，随着海洋资源的开发和利用，海洋受到了严重的污染，其中石油污染尤为突出。海上石油及其产品污染是最重要的生态学灾难性污染之一，海洋石油开采和管道化以及商船运输都是潜在的流动污染源。以微生物为主体的生物修复技术以其投入小、无二次污染的优势被视为最有前途的治理手段。但低水温、寡营养以及海水的冲刷等因素都会直接影响微生物降解石油的效率，加之石油组分的复杂性，使得海洋石油污染的生物修复技术较之其他的生物修复技术更为复杂。本研究针对海洋石油污染治理技术研究领域的难点，开展了石油降解菌的定向驯化、石油降解菌群的构建与优化以及石油降解菌（群）的固定化研究，为成功地运用生物修复技术治理海洋石油污染提供有力...Petroleum is a widespread organic pollutant in marine environments. Crude oil extraction, refining, natural seepage from reservoirs, unregulated disposal by end users, fresh water and terrestrial run-off are all constant sources of marine oil pollution. Biodegradation is one of the most important processes involved in the natural attenuation and eventual removal of petroleum from the environment,...学位：理学硕士院系专业：生命科学学院_微生物学学号：2172009115212

全球化视野下多元文化主义的发展

多元文化主义来源于多民族国家的现实问题,然而,它的概念却是模糊的。近年来,全球化的发展与多元文化主义之间有越来越复杂的关系,全球化的繁荣表面上看是多元文化主义的支撑,在实际发展中全球化也对多元文化主义产生了一定的冲击。在全球化的大背景下,多元文化主义的概念、多元文化主义的道德认可倾向、多元文化主义对全球化发展作用问题依然值得探讨。全球化成为一种不可逆转的趋势之后,多元文化主义为之提供了一种全新的世界秩序模式

Epoxidation of Propylene Catalyzed by Iron-Containing Heterogeneous Catalysts

本论文合成了含铁分子筛，考察了分子筛中不同位置的铁物种在丙烯环氧化反应中的催化反应性能差异，并对催化剂结构进行了详细的表征，进而深入探讨了催化剂结构和性能之间的关联。首先，利用直接水热合成法，模板剂离子交换法和浸渍法合成了铁处于分子筛中不同位置的Fe-MCM-41催化剂，并向其中添加钾盐进行修饰。研究发现，添加KCl后，不同方法合成的Fe-MCM-41均能够实现丙烯氧化由烯丙基氧化向环氧化的转变。多种表征手段结果表明，添加KCl会导致骨架外铁物种由扭曲的八面体结构向为K+离子所稳定的正四面体结构转变，该正四面体结构的铁物种是丙烯环氧化的活性位。对于骨架内四配位的铁物种来说，加入KCl会引起骨架...In this dissertation, KCl modified molecular sieves that contain iron species in- or extra-framework are synthesized to study their different catalytic performances for propylene epoxidation with N2O. These catalysts have been characterized in details and the structure-reactivity relationships have also been investigated. Fe-MCM-41 catalysts are synthesized and iron would be introduced into ...学位：理学硕士院系专业：化学化工学院化学系_物理化学(含化学物理)学号：20022505

朋友圈中辍行为的影响因素研究

随着微信好友数的增加以及微信对工作、生活的全面渗透,越来越多的用户对朋友圈产生了倦怠情绪,并主动减少朋友圈的使用。刘鲁川等学者基于扎根理论,构建出微信倦怠及消极使用模型。在此基础上,本文提炼出可能影响微信用户朋友圈中辍行为的因素,并采用问卷调查法收集数据,使用SPSS23.0对假设进行检验。研究结果表明:1.在长时间使用朋友圈后,微信用户的感知过载、隐私忧虑、上行社会比较及朋友圈倦怠的程度均大于中等水平(李克特5点量表);2.信息过载、社交过载、上行社会比较与朋友圈中辍行为呈负相关关系;3.隐私关注与朋友圈中辍行为无相关关系;4.朋友圈倦怠未在感知过载、上行社会比较与中辍行为间起中介作用

Determination of sulfite in flue gas desulfurization with seawater by ion chromatography

建立了燃煤电厂烟气脱硫海水中亚硫酸根(SO32-)的离子色谱-脉冲安培检测方法。色谱柱为IOnPAC AS14A阴离子交换柱,流动相为14MMOl/l nAOH-12MMOl/l nA2CO3溶液(PH11.7),流速1.2Ml/MIn,脉冲安培法检测。因SO23-易被氧化,故在采样时加入甲醛作为保护剂,使之稳定存在。在测定海水样品前,用nAOH溶液(PH12.0)沉淀海水中的Mg2+,以避免其在PH较高的流动相中生成沉淀堵塞色谱柱。采用该方法检测SO23-的线性范围为0~100Mg/l,平均回收率为116.8%,检出限为0.05Mg/l;对7.5,25.0和75.0Mg/l的海水基底加标溶液分别进行9次平行测定,其相对标准偏差(rSd)分别为2.1%,3.1%和4.0%。该方法具有快速、灵敏、选择性好等特点,用于烟气脱硫的海水中SO32-的检测,可得到令人满意的结果。The technology for flue gas desulfurization(FGD) with seawater is widely adopted by coal-fired power plants in coastal areas.SO2 in the flue gas is absorbed by alkaline seawater and transfered in aqueous phase as sulfite(SO2-3),and most SO2-3 is transformed to sulfate(SO2-4) after an aeration process.The remaining SO2-3 in the seawater discharged to sea area may be harmful to marine organism because of its biological toxicity,thus it is necessary to determine the concentration of SO2-3 in the seawater for desulfurization.In this study,the method of determination of SO2-3 in the seawater by ion chromatography was investigated.The separation was achieved on an IonPac AS14A column with 14 mmol/L NaOH-12 mmol/L Na2CO3 solution as the mobile phase at a flow rate of 1.2 mL/min,and the detection was performed by a pulsed amperometric detector.Formaldehyde was added as a protective agent when sampling because the SO2-3 is easy to be oxidized.To avoid the formation of Mg(OH)2 in the mobile phase with high pH value which might block the column,the Mg2+ in seawater was precipitated by NaOH solution(pH 12.0) before sample determination.The method showed good linearity within the range of 0-100 mg/L with an average recovery of 116.8%.The method detection limit(MDL) reached as low as 0.05 mg/L.The relative standard deviations(RSD) for seawater matrix samples spiked at levels of 7.5,25.0 and 75.0 mg/L were 2.1%,3.1% and 4.0%(n=9),respectively.The method has been applied for the determination of SO2-3 in flue gas desulfurization seawater with the advantages of being fast,sensitive and selective

中国农业物联网及“互联网+农业”进展

本文综述了物联网技术在农业方面的应用和相关技术的研究现状、中国\"互联网+农业\"产业链的组成和现状以及近期制定的相关政策。通过对比总结获得以下结论:中国目前在农业物联网的系统集成方面取得了很大的发展,但是在一些用于农业物联网的原创性传感器方面存在很大的不足;目前农业物联网获取的农业数据应用不足,农业物联网往往处于示范阶段,没有发挥农业物联网应有的作用。由于中国从事农业的劳动人口在减少,耕地也逐渐减少,加上环境问题突出,农业物联网的研究和实施是必然的,因此需要政府继续大力引导和提供必要的支撑条件。中央高校基本科研业务费专项资金(20720150178);;国家自然科学基金面上项目(31771680);;江苏省现代农业基金(BE2015310);;江苏现代农业(蔬菜)产业技术体系智能生产创新团队项目(SXGC[2017]210

Studies on Rice Resistance-related Proteins in Response to Bacterial Leaf Streak,Xanthomonas Oryzae pv.Oryzicola

水稻细菌性条斑病由XAnTHOM OnAS OryzAEPV.OryzICOlA引起,是目前威胁亚洲稻区水稻生产的重要病害之一。以水稻品种9311为研究对象,通过差异蛋白质组学方法,研究了病菌侵染48 H后水稻叶片的差异表达蛋白质,通过分析比对、质谱分析以及数据库检索,从中选择了7个上调表达的鉴定蛋白,包括4个水稻lrk类基因,2个nbS-lrr类基因和1个Pr-10基因家族成员基因。并设计相应的PCr引物,从水稻CdnA中获得相关基因片段做探针进行nOrTHErn杂交分析,结果显示,上述基因在接种病原菌12 H或48 H后表达量增加,表明这些蛋白质参与了抗病反应。Rice bacterial leaf streak(BLS) caused by the pathogen Xanthomonas oryzae pv.oryzicola(Xooc) is one of the major diseases in Asia.In this paper,the protein differently expressed after infected for 48 h by BLS was studied with rice 9311 as material through proteomic approach.Based on the result of protein blast,fingerprints and data search analysis,seven identified proteins up-regulated were selected including four LRK like genes,two NBS-LRR type genes and one PR-10 gene.Relevant primers were designed to amplify the genes from rice cDNA as probe for Northern blotting.The results showed that the mRNA levels of these genes increased significantly after infected by BLS for 12 h and 48 h,indicating these proteins have participated in disease resistance.国家863计划项目(2007AA10Z132);国家重大科技专项(2008ZX08001-001;2009ZX08009-045B);教育部重点项目(重点01102)资
