The Study on the Influence on the Operating Efficiency of China Banks by Introducing Foreign Strategic Investors

近年来，国内一些商业银行为了增加资本金、改善银行管理水平以及提升资本市场信誉等原因，纷纷引进境外战略投资者。境外金融机构也看好中国经济迅速发展所带来的机遇和金融市场的巨大潜力，积极谋求参股我国的商业银行。当各商业银行将目光投向境外，寻求改革突破之时，争论也纷至沓来。中资银行引进境外战略投资者的最终目的是要提高经营效率、增强竞争力。于是，战略引资对银行经营效率的影响就成为理论界争论的焦点问题。战略投资者入股后，中资银行的经营效率是否得到改善，引进战略投资者在银行经营效率的改变中究竟起到多大程度的作用，这些问题需要进行深入的分析。国外学者对一些国家，尤其是转型经济体的银行引进战略投资者的效果进行了...In recent years, in order to increase capital, improve the banking management, as well as to enhance the credibility in capital markets and other reasons, some domestic commercial banks have introduced foreign strategic investors. Foreign financial institutions are also optimistic about China's rapid economic development and opportunities brought by the enormous potential of the financial markets,...学位：经济学硕士院系专业：经济学院金融系_金融学(含保险学)学号：1562006115101

Research on English Teaching Evaluation of Junior High School

在传统的初中英语教学中，考试与考查往往成为学生学习的评价对象，考试的分数成为衡量学生学习成效的唯一评价标准。这种单一片面性的教学评价对于学生的全面发展与教师教学水平的提高有很大的阻碍。 “在英语教学过程中应以形成性评价为主，注重培养和激发学生学习的积极性和自信心。”这是《英语课程标准》提出的新理念，它成为英语教学评价改革的指导思想。英语教师要好好学习这种理念，将形成性评价与终结性评价相结合，并积极贯彻到自己的教学实践中，认真构建一个能激励学生学习兴趣和自主学习能力发展的评价体系。 研究初中英语教学评价问题不仅可以应对英语课程标准提出的新挑战和要求，还能促进教学方法的改革及教师与学生的发展，...In the traditional English teaching of the junior middle school, examination often becomes the evaluation objectives of students' learning and the test score is measured as the only evaluation criterion for students' learning effectiveness. This type of one-sided way of teaching evaluation has become a big obstacle to the all-round development of students and also the improvement of the teaching e...学位：教育学硕士院系专业：教育研究院_教育学学号：X200633000

Study on the effect of chitosan on Deacetylmycoepoxydiene production

海洋微生物生境特殊，具有独特的代谢途径。海洋微生物的次级代谢产物是新药物研究开发的重要资源。如何提高微生物的次级代谢产物的产量，是目前海洋微生物开发亟待解决的问题。近年来，使用诱导子来刺激代谢途径已经成为提高目的产物产量的主要策略之一。 本论文尝试采用诱导子来提高海洋抗肿瘤候选新药去乙酰真菌环氧乙酯(Deacetylmycoepoxydiene，缩写为DAM)的产量，并对诱导机制进行初步的探索。DAM是红树植物内生真菌A123(Phomopsissp.A123)产生的一种骨架新颖的环氧二烯类化合物。前期研究表明，DAM具有较强的细胞毒性，对Raji细胞株IC50为3.0µg/mL...Because of their special living conditions, marine microorganisms often produce various bioactive substances with novel functions and structures. However, the yields of secondary metabolites in the marine fungi are usually too low to carry out further studies on bioactivity or pharmacological properties. Looking for methods to enrich the yield of secondary metabolites is the way to overcoming the ...学位：理学硕士院系专业：生命科学学院生物学系_微生物学学号：2172008115254

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

Structural Characteristics and Sources of the Surface Sediments in Xiamen Coast

为研究厦门近海海域表层沉积物的结构特征、组成及来源,于2010年7月采集厦门湾表层沉积物,综合粒径分析、X射线衍射、扫描电镜等方法对沉积物进行表征。粒径分析的结果表明,沉积物的主体粒径在80μM附近,且有明显的次粒级峰,并以粗颗粒的主体粒级峰占有优势。研究的沉积物类型主要有三种,砂质粉砂、粉砂质砂和砂-粉砂,其中砂质粉砂是分布最广泛的沉积物类型区域沉积物,其含量达90%以上;而粘土含量以背景点鸡屿岛为最高,达到11.97%。X射线衍射分析表明,沉积物中优势轻矿物为石英、高岭石,部分区域含有石墨及一些零星分布的伊利石、海绿石和斜绿泥石。这些矿物组成显示了厦门湾海域表层沉积物具有较好的亲陆性,同时,其组成也受到了涨潮流的较大影响。沉积物形貌形态的研究发现,厦门湾沉积物组分较为复杂,其中含有多种藻类及其碎片(主要为硅藻)、矿物颗粒(高岭石)及未知名碎片;形状主要有孔状结构、层叠状结构、长条片状和不规则的六边形块状等。In order to study the structural characteristic,composition and source of the sediment in Xiamen coastal waters,the surface sediment in Xiamen Bay was collected in July,2010,and the samples were comprehensively analyzed by particle size analysis,X-ray diffraction,scanning electron microscopy and other methods.The results of the particle size analysis showed that the main diameter of the sediment was near 80 μm,with a pronounced secondary pea.There are three main types of sea sediments(sandy silt,silty sand,and sand-silt) and sandy silt is the most widely distributed type,which the content of the silt-sand at all study areas was nearly 90%,while the clay content was highest at the background point and reached to 11.97%.The X-ray diffraction analysis showed that the dominant light minerals in sediments were Quartz,Kaolinite;some areas contained Graphite.Illite,Glauconite and Clinochlore also had been found in some areas accidentally.The mineral composition showed the surface sediments had a good pro-land,meanwhile,it was affected by the flood current.While,the morphology study found that the composition of the sediments at the study areas were complex,containing a variety of algae and debris(mainly diatoms),minerals(kaolinite) and unknown debris.Cavernous structure,stack-like structure,long flake and irregular hexagon were the main shapes in these sediments.国家自然科学基金(41005082);近海海洋环境科学国家重点实验室青年访问学者基金(MELRS1017
