On the African-American Maternal Love in The Bluest Eye

莫里森是美国黑人文学史上最著名的黑人作家之一，其作品描写了黑人的痛苦遭遇，特别是作为劣势群体的黑人女性的悲惨生活。因此，在莫里森的著作中，非裔美国人的母爱是个值得探讨的重要主题。对于>，大多数评论家关注的角度是该小说的种族歧视，女性主义，叙述策略，人物塑造，结构或主题研究。然而，很少人从黑人的母爱对孩子成长的影响的角度来分析该小说。 本文分析《最蓝的眼睛》中两种不同原型的黑人母爱：波林遗失的扭曲的母爱和麦克蒂亚太太持有的坚定的母爱及其各自产生的原因，讨论在种族歧视和白人文化压迫下，两种不同母爱对她们的孩子佩科拉和克劳蒂亚的命运产生的不同影响。佩科拉出生在一个残缺、不正常的家庭，她妈妈具有毁灭...Toni Morrison is one of the most prominent black writers in African-American literature whose novels dedicate to depicting the sufferings of the African-American people, especially the miserable life of African-American women as an inferior group. Therefore, the African-American maternal love is a significant theme worthy of consideration in Toni Morrison's works. On The Bluest Eye, most critics e...学位：文学硕士院系专业：外文学院_英语语言文学学号：K20110403

Acoustic logging technology research

声波测井从上世纪50年代开始，经历了几十年的发展，已经 成为测井研究的重要领域，是当今发展最快和应用最为广泛的现代测井方 法。声波测井是油气矿藏勘探和开发的最为重要的手段之一。为了满足复 杂油气矿藏的勘探开发，投入了大量资金开展声波测井方向的研究。 声波测井的物理基础是研究与岩石特性密切相关的声振动沿钻井方 向的传播特性，特点是记录了地层的纵波、横波及流体波的时差、幅度、 频率、相位等信息，而这些信息对于计算孔隙度、判断岩性、定性识别流 体性质、评价岩石力学弹性参数等具有重要的作用，并且还可以为较深的 砂泥岩储层估算岩石破裂压力值，为油藏工程提供参数，因此声波测井是 油气勘探...Since the beginning of the last century in 50s, sonic logging has experienced several decades of development, it has become an important field of well logging research, and it is the most widely used modern well logging method. Acoustic logging is one of the most important tools for the exploration and development of oil and gas deposits. In order to satisfy the exploration and development o...学位：工程硕士院系专业：信息科学与技术学院_工程硕士(电子与通信工程)学号：X201122203

Design and Implementation of Bank Salary Management System

随着经济飞速发展，职员工资管理成了许多银行需要面对的问题。某银行规模的不断扩大，与之相关的信息也不可避免的急剧增长。在这样的形势下，手动处理员工的工资信息不仅使人力不从心，而且极其容易出错。而将现代计算机技术以及先进的管理理论引入银行管理中，使用网络技术开发一套满足银行工资管理需求的管理系统，并通过该系统促进管理决策层人员交流，构建员工管理平台，促进考核以及工资信息的收集，进一步规范管理流程，已成为目前银行工资管理工作的迫切要求。 银行工资管理系统主要是实现银行工资管理的信息化，对现有的工资管理制度进行改革从而提高工资管理效率。系统主要进行模块化设计，主要是由个人工资查看、个人信息修改、个人...With the rapid development of economic, the management of employees' salary becomes the question which is many banks should face. Because of continuous expansion of bank scale, some associated information inevitably grows rapidly. In this kind of situation, manual processing employees' salary information not only makes their ability falls short of their wishes, but it makes them be very prone to e...学位：工程硕士院系专业：软件学院_工程硕士(软件工程)学号：X201323031

Vibration Damping of Carbon Nanotube Assembly Materials

Vibration reduction is of great importance in various engineering applications, and a material that exhibits good vibration damping along with high strength and modulus has become more and more vital. Owing to the superior mechanical property of carbon nanotube (CNT), new types of vibration damping material can be developed. This paper presents recent advancements, including our progresses, in the development of high-damping macroscopic CNT assembly materials, such as forests, gels, films, and fibers. In these assemblies, structural deformation of CNTs, zipping and unzipping at CNT connection nodes, strengthening and welding of the nodes, and sliding between CNTs or CNT bundles are playing important roles in determining the viscoelasticity, and elasticity as well. Towards the damping enhancement, strategies for micro-structure and interface design are also discussed

Detection of incoherent broadband terahertz light using antenna-coupled high-electron-mobility field-effect transistors

The sensitivity of direct terahertz detectors based on self-mixing of terahertz electromagnetic wave in field-effect transistors is being improved with noise-equivalent power close to that of Schottky-barrier-diode detectors. Here we report such detectors based on AlGaN/GaN two-dimensional electron gas at 77~K are able to sense broadband and incoherent terahertz radiation. The measured photocurrent as a function of the gate voltage agrees well with the self-mixing model and the spectral response is mainly determined by the antenna. A Fourier-transform spectrometer equipped with detectors designed for 340, 650 and 900~GHz bands allows for terahertz spectroscopy in a frequency range from 0.1 to 2.0~THz. The 900~GHz detector at 77~K offers an optical sensitivity about $1~\mathrm{pW/\sqrt{Hz}}$ being comparable to a commercial silicon bolometer at 4.2~K. By further improving the sensitivity, room-temperature detectors would find applications in active/passive terahertz imaging and terahertz spectroscopy.Comment: 4.5 pages, 5 figure
