Experimental study on adhesion mechanism of two marine benthic diatoms

海洋底栖硅藻是海洋生态系统中重要的单细胞真核生物类群，经常附着在浅海底部、潮间带的泥沙滩、岩石和动植物表面以及各种人工设施上，是常见的海洋污损生物之一，对人类海洋工程设施造成很大危害。底栖硅藻主要依靠分泌的胞外多聚物附着在基质表面，其生长和胞外多聚物分泌受光照、水体温度、盐度、营养盐等的显著影响，对环境因子的变化反应敏感。但不同底栖硅藻种类其生长特性、生化组分、附着形式、附着基的组分与受控因素也不同。目前关于海洋底栖硅藻附着机制的研究还很有限，尤其是附着行为与环境因子间的关系及生理响应方面的研究比较薄弱。研究不同底栖硅藻的附着机制对海洋底栖生态系统和污损生物研究具有重要的理论和实际意义。 本...Marine benthic diatom is an important kind of unicellular eukaryotes in marine ecosystem. They usually attach on the shallow sea seafloor, intertidal zone, rocks and animals and plants surface, as well as artificial facilities, and they may cause great harms to marine artificial engineering facilities as one of fouling organisms. Marine benthic diatoms attach on substrate surfaces by secreting ext...学位：理学硕士院系专业：生命科学学院_水生生物学学号：2162014015418

Theoretical Studies of Structures and Properties of Coals

煤炭是我国的主体能源，但煤炭资源总量的40%为低品质煤，针对这部分资源开展计算模拟研究，对煤化学的发展和煤资源提质与优化利用具有积极意义。煤是由多个结构相似的基本结构单元通过桥键连接而成的大分子网状结构的混合物，其分子结构和相关的物理化学性质还不是很清楚。量子化学计算作为原子分子水平上研究复杂体系的理论工具，在煤结构与性质的研究中逐渐获得应用。本文通过密度泛函计算，对几类代表性煤分子的结构、光谱性质、裂解性质和持水性质进行了计算研究，获得的主要结果如下: (1)通过理论计算，预测了四类典型煤模型分子的结构和光谱性质，结合相关的实验表征，构建了一类褐煤的结构模型，计算得到的光谱与实验光谱符合得...Coal is the dominant energy resources in China, but 40% of the total coal resources are the low-rank coals. It is thus highly required for the efficient utilization and upgrading of low-rank coals and the development of coal chemistry to carry out computational simulations on this part of the resources. Generally, coal has a complicated macromolecular network structure consisting of different size...学位：理学硕士院系专业：化学化工学院_物理化学(含化学物理)学号：2052010115158

The Relationship between Tocopherol Cyclase Gene(VTE1) from Arabidopsis and Content of Vitamin E and Tolerance in Tobacco W38

生育酚又称维生素E（VE），是一类重要的脂溶性抗氧化剂，是植物在逆境下细胞膜上重要的效应物。生育酚环化酶（TC）催化形成抗氧化芳香环并最终形成相应的生育酚，在拟南芥中TC是由VTE1编码的。本实验利用根癌农杆菌(Agrobacteriumtumefaciens)介导法在烟草中过量表达拟南芥来源的VTE1，检验其对提高烟草维生素E含量的效应。同时为验证生育酚水平与外界胁迫程度的相关性，本实验还研究了转基因烟草对高光强、高盐等胁迫条件的耐受性，为植物抗逆机理的研究奠定基础。主要实验结果如下：Southern杂交和RT-PCR检测发现有10株转基因烟草扩增出特异条带，经测定，转基因烟草的VE含量普遍...Tocopherol is also called vitamin E (VE), it is one kind of the important lipophilic antioxidant on cell membrane for plants under the stressful environments.

In this study, tobacco W38 was transformed with a construct conta...学位：理学硕士院系专业：生命科学学院生物学系_发育生物学学号：20032604

Study on Impact of Discharging Desulfurized Seawater of Coal-fired power plant on Marine Environment and Analysis Method of Typical Water Quality Indexes

本论文研究了燃煤电厂海水烟气脱硫（SeawaterFlueGasDesulfurization,SWFGD）工艺造成的海水水质变化，及脱硫海水排放后对附近海域环境的影响。SO2是导致大气污染的主要酸性气体之一，给生态环境、人类健康、文化古迹等带来重大的危害和损失。火电厂是SO2的排放大户，因此，有效控制火电厂SO2的排放，成为大气污染治理的首要任务。烟气脱硫是控制SO2排放的最为有效和主要的技术手段，其中，SWFGD法直接利用海水的天然碱度洗涤、中和烟气中的SO2，脱硫后的海水经过曝气后直接排向大海，具有运行成本低、投资少、系统简单、无固态废弃物等特点，成为沿海地区各火电厂烟气脱硫的首选方法。...The variation of seawater quality and impact of discharging desulfurized seawater on the sea area due to the seawater flue gas desulfurization (SWFGD) has been studied in this dissertation. It is well known that SO2 is one of the main acid gas sources, which can cause serious damage to ecological environment, human heath and cultural ashes. Coal-fired power plant is one of the largest pollution so...学位：理学硕士院系专业：海洋与环境学院环境科学与工程系_环境科学学号：2122005130221

Allegorical Impulse: On Donald Barthelme’s Textual Practice

唐纳德•巴塞尔姆以对文学形式的大胆革新和文学经典的创意改写在美国后现代派作家中独树一帜，却也是长期被误读的作家之一，这从国内外学界的研究状况或可略见一斑：就美国评论界而言，巴塞尔姆作品中某主人公的一句话“断裂是我信任的唯一形式”时常被援引为其本人的美学宣言和创作理念，此后一切关乎巴塞尔姆之评论莫不以“碎片”、“形式”、“无深度性”等后现代“御用”字眼为纲，导致评论千篇一律，对其作品的研究则长期停滞不前；在中国，从学界到读者对巴塞尔姆的认知大多仅限于他那部著名的戏仿之作《白雪公主》，各种评论文章皆出于此，另有零星数篇是对其短篇小说的译介，但缺乏对作家全部作品的整体研究。针对这一研究现...Donald Barthelme distinguishes himself in postmodernist American literature by his brilliant experiments with literary forms and his daringly amazing employment of the past literary and cultural sources. Yet he is among the writers who have been misunderstood for long.

Globalization in Maxine Hong Kingston's Tripmaster Monkey:His Fake Book

摘要汤亭亭（又名马克辛.洪.金斯顿）是著名的美国华裔女作家，曾以半自传体姐妹篇《女勇士》（1976）和《中国佬》（1980）而轰动文坛。作为一个少数族裔作家，汤亭亭从不认为少数族裔作家及其作品应当被归为特定的一类文学，而指出优秀的作品，即使是出自少数族裔作家之手，亦应在世界文学宝库中占有一席之地。她本人也努力尝试通过全球化写作实践来赋予作品深度和广度，以摆脱少数族裔作家的樊篱。《引路人孙行者:他的即兴曲》（1989）为其第一部小说，书中反映了她在全球化文化背景下对一系列问题的思考，是研究其全球化思想发展趋势的绝好文本。文化属性问题是少数族裔作家在文学创作中决不会忽视的主题。作品里拥有双重乃至多...Synopsis Maxine Hong Kingston, the famous Chinese American woman writer, is best known for her two companion semi-autobiographies The Woman Warrior (1976) and China Men (1980). An ethnic writer as she is, she never thinks that ethnic writers and their works should be confined to a particular category. Instead, she argues that great works by ethnic minority should not be denied a place in t...学位：文学硕士院系专业：外文学院外文系_英语语言文学学号：20030400

汤亭亭"全球化文学创作"的构想与试验——评长篇小说《引路人孙行者:他的即兴曲》

华裔女性作家汤亭亭第一部真正意义上的小说《引路人孙行者》是其致力于“全球化小说“(glObAlnOVEl)创作的初次实践。通过对于“全球化“文化叙事问题的探讨,汤亭亭借助这一小说来反映全球化语境下文化身份的多元性和流动性,并试图通过个体与群体的重新塑造来探讨走向现代人精神家园的理论与方法,因此,作为其“全球化文学创作“的一个试验,这部小说不仅反映出其全球化小说的理论构想,同时也为全球化语境下文学创作与文学研究提供了一个思路与方法。Tripmaster Monkey,claimed to be Kingston's first novel,is her first literary attempt on creating a global novel.Focusing on the issue of cultural discourse in the context of globalization,Kingston is aiming at catching the tempo of our age,a trend towards globalization characterized by the multiplicity and fluidity of both the personal and the communal identity,and at raising a theoretical method of creating the spiritual home for the modern people by remodeling both the individual and the community.This novel well reflects her theoretical construction of "the global novel" ,and also provides a way for literary creation and research in the context of globalization

On the Principle of Best Interests of Children in Divorce Cases

“儿童最大利益原则”是20世纪末以来国际公约和各国立法逐步确立的一项权利保护的重要原则。据此原则，涉及儿童的一切行为均应以儿童最大利益为首要考虑。在离婚案件中，儿童作为无过错主体无论是精神上还是物质上都受到极大地伤害，理应对其进行特殊保护。我国虽提出“儿童优先原则”作为保护儿童权益的指导原则，但在实践中所起的作用较小。本文立足于我国现实，在借鉴其他学者研究成果的基础上，主要运用比较法学方法、实证分析法学方法等对儿童最大利益原则在离婚案件中的适用进行研究，介绍国外离婚案件中儿童最大利益原则的适用，分析其子女本位的立法观念和完善的制度性设置，同时对我国离婚法律制度涉及儿童利益的相关规定进行反思，提...The principle of best interests of children has been the most important principle to protect children’s right in the international conventions and nations since the end of the 21th century. On the basis of this principle, the best interests of children must be the paramount consideration when it involves all of the children’s acts.
