Identification but not Homogenization: On Mimicry in Zadie Smith’s White Teeth

本文对英国牙买加裔女作家扎迪•史密斯的处女作《白牙》做文本分析，运用霍米•巴巴的模拟理论，讨论了该书里不同世代的移民如何努力获得身份认同、融入英国社会，旨在从时间性的角度，强调在当前的后殖民英国里存在着第三空间。不同世代的移民在构建身份的过程中遭遇英格兰民族主义，采取了单一或是双向的模拟方法，从而在种族话语、宗教、国家认同等方面产生了世代差异。本文认为后殖民的第三空间不允许种族和文化同质化，其间，移民在认同过程中构建起的身份包含着诸多元素，相互作用，具有时间性。 第一章概述巴巴的模拟理论，以及它在过去的殖民地和现在的西方国家里的体现，强调了该策略与种族密不可分。因为模...This MA thesis uses Jamaican British writer Zadie Smith’s debut novel White Teeth as the case study. With the employment of Homi Bhabha’s strategy of mimicry, it explores the identification of generations of immigrants in the postcolonial Britain. Different from previous reviews of the book, the thesis takes the perspective of temporality, stressing the existing being of the Third Space in today’s...学位：文学硕士院系专业：外文学院英语语言文学系_英语语言文学学号：1202006115031

Diversity of bacterial community structure and its driving factors in three bays of Bohai Sea

[Background] Sustainable development of coastal ecosystem has become one of the most important concerns for people nowadays. Riverine output and anthropogenic interrupt have important impacts on the coastal environment. [Objective] In this study, we collected 12 samples from three transects including Bohai Bay, Liaodong Bay and Laizhou Bay to explore the microbial community and diversity in summer of 2015. [Methods] DNA was extracted from water samples by using DNA extraction kit. Samples were analyzed by Illumina HiSeq sequencing technology. We compared the differences among these three transects according to the analysis results. [Results] The diversity index and rarefaction curves showed significant differences among these three transects. The order of diversity value was Laizhou Bay>Bohai Bay>Liaodong Bay. The distribution of the dominant community was as follows: the proportion of Proteobacteria, Bacteroidetes, Cyanobacteria, Actinobacteria and Planctomycetes in the Bohai Bay was 39.8%, 25.7%, 22.4%, 5.85% and 4.38%, respectively. The dominant community proportion in Liaodong bay was Proteobacteria (37.8%), Bacteroidetes (25.7%), Cyanobacteria (17.8%), Actinobacteria (10.4%) and Planctomycetes (5.64%). While in Laizhou Bay there were only four dominant communities as follows: Proteobacteria (59.0%), Bacteroidetes (17.5%), Cyanobacteria (8.2%), Actinobacteria (7.88%). By using the principal component analysis (PCA) and Heatmap correlation analysis, we found that environmental factors were key roles in controlling the microbial diversity in the Bohai Sea. Among them, the concentration of nitrate was particularly significant according to the Mantel test analysis. [Conclusion] The microbial diversity in the three bays of Bohai Sea was very rich and multifarious. The population structure and species in the Laizhou Bay is the most complex and abundant among these three bays, and then it is Bohai Bay and Liaodong Bay. There was a significant correlation among microbial diversity, environmental factors and the spatial distribution. Above all, this study will provide a theoretical basis for further protection and ecological development of Bohai Sea

Study on removal boron from solargrade silicon with hydrometallurgy

湿法提纯作为冶金法制备太阳能级硅的前处理工序,可以去除大部分金属和硼杂质。研究了以氢氟酸-硫酸混合酸为浸出剂,有机溶剂甲醇作为后处理剂,去除硅粉中硼杂质的方法。采用电感耦合等离子体发射光谱仪(ICP)等对产品进行表征。酸浸过程优化工艺条件:硫酸质量分数为55%,氢氟酸质量分数为7%,酸浸温度为70℃、酸浸时间为4 H、液固质量比为8∶1。酸浸后可使硅粉中的硼杂质质量分数由6.893x10-6降至3.867x10-6,去除率为41.9%。在酸浸基础上采用有机溶剂甲醇作为后处理剂,杂质硼质量分数降至3.84x10-6,去除率为44.29%。从硼酸浸后形成的产物入手探索提高硼去除率的方法,实验验证了该方法的可行性,为研究湿法冶金预处理太阳能级硅提供了新的参考。As a pretreatment unit for preparing solargrade silicon(SG-Si) by metallurgic method,wet purification could remove most metallic impurities and nonmetallic impurities,such as boron.Experiment researched a new method to remove boron from SG-Si with mixed hydrofluoric acid-sulfuric acid as leaching agent and with organic solvent methanol as posttreatment agent.Samples were characterized by ICP and other analysis methods.When SG-Si powder had been leached at optimized conditions as follows:mass fraction of sulfuric acid was 55%,mass fraction of hydrofluoric acid was 7%,reaction temperature was 70 ℃,reaction time was 4 h,and liquid-solid mass ratio 8∶1,it was found that mass fraction of impurity boron in SG-Si was reduced to 3.867×10-6 from 6.893×10-6 and the removal rate was 41.9% after acid leaching;on the basis of the former procedure,mass fraction of impurity boron was reduced to 3.84×10-6 and the removal rate was 44.29% when treated with organic solvent.Experiment proved the feasibility of the method and provided a new reference for researching on the pretreatment of SG-Si by hydrometallurgy

基于生物质谱技术的磷酰化修饰策略在多肽测序中的应用

该文建立了一种利用磷酰化修饰结合电喷雾质谱(ESI-Q-TOF)测定多肽氨基酸序列的有效方法。利用Atherton-Todd反应,以二丙基亚磷酰酯(DPP)为磷酰化试剂,应用生物质谱技术,对磷酰化修饰后的5种模型肽的磷酰化反应情况进行了系统研究,考察了磷酰化肽的二级质谱特征,并与未经磷酰化反应的肽的二级质谱特征对比。结果表明,经过磷酰化修饰后,肽的二级质谱中的a1离子信号强度明显增加,可以准确鉴定其N端氨基酸;b系列离子信息完整,信号强度增强,使得多肽C ID测序的谱图简单、清晰,有利于肽的氨基酸序列的测定;赖氨酸(K,128.10 u)和谷氨酰胺(Q,128.13 u)两种氨基酸质荷比相近,由于二者磷酰化修饰后的差异性,使其得到准确区分。经过5种已知氨基酸序列的模型肽的磷酰化后结合质谱技术进行氨基酸序列测定验证,结果表明该方法简单、快速、准确,提高了利用质谱技术进行多肽测序的准确度和灵敏度,可为蛋白质组学研究提供有效的技术手段
