加入WTO对我国银行业的影响及对策

1999年11月15日中美双方结束了就中国加入WTO双边谈判，这使我国在加入世贸组织的进程中迈出了关键的一步，而银行服务业作为金融业的主要方面又是美国及欧盟等发达国家的主要要价所在。当然我们也知道中国加入WTO，银行业务的大开放只是早晚的事。对银行业来说，对外开放肯定会给中国带来机遇的同时也带来严峻的挑战，那么我们中国银行业应该如何做呢？本文主要分三个部分进行了阐述： 第一部分主要论述了我国银行业对外开放的历程及现状，由此看出，随着我国加入WTO的步伐加快，外资银行的进入也将随之加快，这势必给国内银行带来机遇和挑战。 第二部分对入世给我国银行业带来的机遇和挑战分别进行了论述。首先论述了加入...学位：经济学硕士院系专业：经济学院财政金融系_金融学(含保险学)学号：B19993106

含镁离子电解质对氧化铝浆料流变性能的影响

通过高纯氧化铝陶瓷浆料粘度和zeta(ζ)电位等参数的考察,探讨了不同pH值下,含镁离子电解质对其流变性能的影响。结果表明,镁离子会降低氧化铝浆料的流变性能。在其存在下,无分散剂时与添加聚丙烯酸(PAA)作分散剂时,pH值分别为6.5和9.5的浆料具有良好的流变性能。无镁离子存在时,PAA的最佳添加量为0.5%;镁离子浓度为0.05mol/L时,该量增加至0.9%

The Hydraulic Cylinder with Extensive Position Controlled Piston Rod

该文介绍了一种活塞杆伸出量可测并可控的液压缸。该缸利用滚珠丝杆将活塞杆的直线位移转化为丝杆角位移的方法进行位置测量,其结果由光栅编码器输出并传送到控制中心,由控制中心控制伺服阀的阀口方向和开口大小,从而对液压缸活塞杆产生控制作用。本文对其原理进行了阐述,并对可能存在的测量误差进行了分析。This paper introduces a hydraulic cylinder that its piston rod extension can be effectively controlled,linear displacement of the piston rod can be changed into the screw angular displacement by ball screw,then the distance are outputted by grating angular displacement sensor to the control center,valve port opening direction and size are controlled by the control center and then hydraulic cylinder piston rod is controlled so.This paper describes its principles and demonstrates its feasibility

压缩拐角激波与旁路转捩边界层干扰数值研究

为了研究激波与旁路转捩边界层的干扰机理,采用直接数值模拟(DNS)方法对来流马赫数Ma∞=2.9,24°压缩拐角内激波与转捩边界层的相互作用进行了系统的研究。考察了旁路转捩干扰下压缩拐角内分离区形态和激波波系结构的典型特征。比较了转捩干扰与湍流干扰流动结构的差异,并分析了造成差异的原因。研究了拐角内转捩边界层的演化特性,探讨了转捩干扰下脉动峰值压力和峰值摩阻的分布规律及形成机制。研究结果表明:相较于湍流干扰,两侧发卡涡串的展向挤压使得分离区起始点以V字型分布,且分离激波沿展向以破碎状态为主,激波脚呈现多层结构;拐角内的干扰作用急剧加速了边界层的转捩过程;转捩干扰下的拐角内峰值脉动压力以单峰结构出现在分离区的下游,同时干扰区内的强湍动能和高雷诺剪切应力使得其局部峰值摩阻系数要高于湍流干扰

MODELING of LOOP REACTOR FOR POLYPROPYLENE SPHERIPOL TECHNOLOGY

在ASPEn POlyMErS PluS软件平台上模拟SPHErIPOl聚丙烯工艺中核心液相环管反应器,采用了等效的全混流反应器模型和组合式环管反应器模型,结合工厂现场采集的数据,拟合了丙烯聚合反应动力学模型,并将该模型用于2种环管反应器模拟方法的比较。采用组合式环管反应器模型考察了丙烯聚合反应循环比对反应器撤热、聚丙烯产量和相对分子质量分布、反应器内氢气浓度分布的影响。结果表明,在高循环比操作条件下和误差允许范围内,环管反应器可以等效为一个全混流反应器。当控制环管反应器夹套冷却水出口温度不变时,过低的循环比使得反应器内的温度分布不均匀,而过高的循环比则使环管反应器的撤热能力下降;当循环比增加时,环管反应器内的温度和组分浓度梯度减小,停留时间分布均匀,趋于全混流状态,催化剂活性得到充分发挥,聚丙烯产量也相应增加。Both the continuous stirred tank reactor model and the combined tubular loop reactor model were set up to simulate the steady-state performance of the industrial tubular loop reactor of Spheripol technology of propylene polymerization based on the Aspen Polymers Plus software.A comprehensive catalyzed polymerization kinetic model was verified by using plant data,and was employed to analyze the operational performance of the two models.It was observed that in high recycle ratio for propylene polymerization,the tubular loop reactor could be simulated,to a certain error degree,by a continuous stirred reactor.In addition,the effects of recycle ratio on the performance of the loop reactor could also be obtained via the combined model.The simulated results showed that the low recycle ratio made the temperature change along the tubular loop reactor in a large range under the constant coolant outlet temperature,while the high recycle ratio made the reaction temperature uniform in the tubular loop reactor,but the capacity of heat evacuation reduced.On the other hand,with the increase of recycle ratio,the concentration gradients of reaction components were lowered,and the polypropylene production was enlarged,approaching to the performance of the continuous stirred reactor.中国石油天然气股份有限公司兰州石油化工研究中心项目(2008015)资

CCCCC pentadentate chelates with planar Möbius aromaticity and unique properties

本课题充分发挥了厦门大学多学科协同研究优势，通讯作者为夏海平教授（合成、表征）、刘刚教授（生物医学应用）和吕鑫教授（理论计算）。合成实验和结构表征由朱从青（第一作者，目前在麻省理工学院、2005年诺贝尔化学奖得主Richard Schrock教授课题组从事博士后研究）完成；生物医学应用由杨彩霞（共同第一作者）、林凎、杨宇惠、王晓勇合作完成；理论计算由朱军、王永恒、朱从青完成。美国NIH的陈小元教授参与了生物医学应用的讨论。该研究工作得到国家自然科学基金委、科技部项目的支持。The coordinating atoms in polydentate chelates are primarily heteroatoms. We present the first examples of pentadentate chelates with all binding atoms of the chelating agent being carbon atoms, denoted as CCCCC chelates. Having up to five metal-carbon bonds in the equatorial plane has not been previously observed in transition metal chemistry. Density functional theory calculations showed that the planar metallacycle has extended Craig-Möbius aromaticity arising from 12-center–12-electron dπ-pπ π-conjugation. These planar chelates have broad absorption in the ultraviolet-visible–near-infrared region and, thus, notable photothermal performance upon irradiation by an 808-nm laser, indicating that these chelates have potential applications in photothermal therapy. The combination of facile synthesis, high stability, and broad absorption of these complexes could make the polydentate carbon chain a novel building block in coordination chemistry.the National Basic Research Program of China (nos. 2012CB821600 and 2014CB744503) , the National Science Foundation of China (nos. 21332002, 81422023, 51273165, 21490573, and 21573179)
