Design and Implementation of Electronic Operation Maintenance System for Telecom Industry

伴随着计算机与Internet技术的发展促进了电信行业的飞速发展，电信市场竞争变得越来越激烈，市场营销策略需要样式多变，客户需要更加个性化的服务。运行维护是电信行业重要的工作之一，然而，在传统手工运维管理方式下，进行一次运维工作可能需要几个小时甚至几天的时间，这种落后运维管理方式已经阻碍了电信行业的发展。所以，利用网络技术和信息化技术对当前的运维管理进行了优化设计，对电信行业运维的业务需求进行深入分析，开发一个电信行业电子运维系统，已经成为迫在眉睫的事情。本文根据电子运维滚里的需求和对用户的分析，首先，进行了调研；然后进行了系统的总体设计和详细设计，重点对电子工单管理、统计报表管理等模块进行设...With the development of computer and internet technology, the development of communication industry technology becomes rapid.along with the development of communication industry the market is becoming more and more competitive, the various marketing strategy is needed, and also the more personalized service is asked by customer.

The Research on Lao She's Translation in 1930s

老舍是中国现代文学史上著名的作家，但他的翻译实践却长期不为人所知。事实上，从目前的研究成果上看，老舍共著有16部译文，其规模为25万字左右。因此，为全面、深入、彻底地了解老舍起见，其翻译实践很值得我们进行深入研究。 鉴于老舍的16部译文中有14部作于20世纪30年代，并且这一时期也是老舍创作活动的鼎盛时期（《骆驼祥子》、《离婚》、《月牙儿》等均作于此时），本文决定以老舍于20世纪30年代的“英译汉”翻译实践为研究对象，对老舍于这一时期的翻译实践策略，翻译对其同期创作产生的影响以及其翻译实践中止的原因进行研究，从翻译学、比较文学与文学史的角度理清老舍翻译实践的总体风貌。 全文共分四个部分： ...In Modern Chinese Literature, Lao She has enjoyed high reputation with his literary works. However, it is obscure to almost everyone that meanwhile he has assumed a translator's role. In fact, as a translator, Lao She translated at least 16 works, nearly 25, 000 words in total. Given the truth mentioned above, we insisted that Lao She’s translations be studied and valued, so that we could read Lao...学位：文学硕士院系专业：人文学院_中国现当代文学学号：1022011115224

A dataset of land cover classification in 25 port cities and their surrounding areas along“One Belt and One Road” (2015)

利用2015年成像的Landsat 8 OLI多光谱影像，参考全球30 m土地覆盖数据（GlobeLand30）的分类标准、制图规范，建立&ldquo;一带一路&rdquo;港口城市土地覆盖分类系统，运用ENVI 5.2软件，基于支持向量机的监督分类方法，对&ldquo;一带一路&rdquo;海上丝绸之路沿线的25个重要港口城市及其周边区域的土地覆盖进行遥感分类，经过严格的修改与精度验证工作，得到土地覆盖分类数据。本数据集可用于土地利用变化、生态环境变化研究，能够清晰反映港口城市建成区及其周边地区的生态环境现状特征。</p

下调基因PTTG1对人胶质瘤细胞SHG44增殖、凋亡、迁移和侵袭能力的影响

背景与目的:研究表明垂体瘤转化基因1(pituitary tumor-transforming gene 1,PTTG1)在多种癌症中高表达。该研究旨在探讨其对胶质瘤细胞SHG44增殖、凋亡、迁移和侵袭能力的影响。方法:用PTTG1 siRNA干扰胶质瘤细胞SHG44的基因表达,通过实时荧光定量聚合酶链反应(real-time fluorescence quantitative polymerase chain reaction,RTFQ-PCR)和蛋白质印迹法(Western blot)分别在mRNA和蛋白质水平上评估PTTG1沉默效率,进一步检测其对SHG44细胞增殖、凋亡、迁移和侵袭能力的影响。结果:沉默PTTG1基因表达可以显著抑制SHG44细胞增殖(P<0.05)、迁移(P<0.01)和侵袭(P<0.001)能力,增加细胞凋亡(P<0.05)。结论:下调PTTG1的表达可以降低神经胶质瘤的恶化程度,有望成为临床胶质瘤治疗的新靶点。福建省自然科学基金(2016D019);;\n福建省卫计委医学创新项目(2016-CXB-12

Electrocatalytic Activity of Palladium Nanocatalysts Supported on Carbon Nanoparticles in Formic Acid Oxidation

采用化学还原法制备了碳纳米粒子支撑的钯纳米结构(Pd-CNP). 透射电镜表征显示在Pd-CNP纳米复合物中，金属Pd呈菜花状结构，粒径约20~30 nm。它们由许多更小的Pd纳米粒子（3~8 nm）组成. 电化学研究表明，虽然Pd-CNP的电化学活性面积比商业Pd黑低40%（可能原因是部分Pd表面被一层碳纳米粒子覆盖），但其对甲酸氧化却表现出更好的电催化活性：质量比活性和面积比活性都比Pd黑高几倍. 催化活性增强的原因可能是碳纳米粒子支撑的Pd纳米结构具有特殊的层次化结构，可以形成更多的活性位，以及表面位更利于反应进行.Palladium nanostructures were deposited onto carbon nanoparticle surface by a chemical reduction method. Transmission electron microscopic studies showed that whereas the resulting metal-carbon (Pd-CNP) nanocomposites exhibited a diameter of 20 to 30 nm, the metal components actually showed a cauliflower-like surface morphology that consisted of numerous smaller Pd nanoparticles (3 to 8 nm). Electrochemical studies showed that the effective surface area of the Pd-CNP nanoparticles was about 40% less than that of Pd black, possibly because the Pd nanoparticles were coated with a layer of carbon nanoparticles; yet, the Pd-CNP nanocomposites exhibited marked enhancement of the electrocatalytic activity in formic acid oxidation, as compared to that of Pd black. In fact, the mass- and surface-specific activities of the former were about three times higher than those of the latter. This improvement was likely a result of the enhanced accessibility of the Pd catalyst surface and the formation of abundant active sites of Pd on the carbon nanoparticle surface due to the hierarchical structure of the metal nanocatalysts.This work was supported, in part, by the National Science Foundation (CHE&ndash;1012256 and DMR&ndash;0804049) and by the ACS-Petroleum Research Fund (49137&ndash;ND10).
