Research and Implementation of Rural Cooperative Financial Institution Integrated Business Network System

随着社会经济的发展与信息技术的进步，各商业银行相继建立了行内资金清算网络和金融服务信息平台，为客户提供实时资金清算和个性化金融服务，而农村合作金融机构（包括农村信用社、农村商业银行及农村合作银行）的特约电子汇兑系统的结算方式（仅限于本省农村合作金融机构的结算方式）远远落后于商业银行，成为业务进一步发展的瓶颈。为适应全国农村合作金融机构业务发展的形势，满足农村合作金融机构跨省清算的需要，需要建立一个农村合作金融机构综合业务网络系统（以下简称“农信银系统”），担负起农村合作金融机构跨省资金清算的职能，服务于农村基层金融，为农村支付业务提供快速便捷的清算服务。 本文以建设一个信息化的农信银系统为出...As the development of social economy and the progress of information technology, commercial banks have established the internal fund settlement network and financial information services platform, providing real-time fund settlement and personalized financial services. However, rural cooperative financial institutions (including rural credit cooperatives, rural commercial banks and rural cooperati...学位：工程硕士院系专业：软件学院_工程硕士(软件工程)学号：X200923027

Fabrication of semiconducting Cu/Cu_2O dispersive composite thin films with metallic resistivity and the bias voltage effect

采用平衡直流磁控溅射技术,通过改变衬底偏压在玻璃衬底上制备了Cu/Cu_2O弥散复合薄膜,并利用扫描电子显微镜、X射线衍射仪、四探针测试仪和紫外-可见分光光度计等进行表征与分析。研究发现,Cu/Cu_2O弥散复合薄膜表现出金属和半导体双特性,其电阻率范围为(5.23~9.98)×10-5Ω·cm,禁带宽度范围为2.23~2.47eV。同时,研究还发现衬底偏压对Cu/Cu_2O弥散复合薄膜的形貌、结构、电学和光学性能都产生了较大的影响,特别是当衬底偏压为-100V时薄膜样品的表面最为致密,结晶程度最好,电阻率最低,禁带宽度最窄。进一步地,对平衡磁控溅射过程的偏压效应进行了分析,并提出了两种区别于传统轰击和再溅射作用的新机制。Cu/Cu2 O dispersive composite thin films were successfully fabricated on glass slides using direct current-balanced magnetron sputtering technology by changing the substrate bias voltage.Scanning electron microscope,X-ray diffractometer,four-point probe instrument and ultraviolet-visible spectrophotometer were applied for a detailed characterization.It was found that as-prepared composite thin films show an intriguing combination of metal and semiconductor characteristics with resistivity of(5.23-9.98)× 10-5Ω·cm and bandgap of2.23-2.47 eV.It was also found that the substrate bias voltage influences the morphology,structure,electrical and optical properties greatly.Especially,when the substrate bias voltage was-100 V,as-prepared composite thin film presents a condensed morphology and a well-crystallized structure with the lowest resistivity and the narrowest bandgap.Further,the bias voltage effect during balanced magnetron sputtering deposition was studied and two new mechanisms which differentiate from the traditional bombardment and re-sputtering mechanisms were also proposed.江苏省自然科学基金资助项目(BK20141169);; 江苏省高等学校大学生实践创新训练计划资助项目(201410292032Y);; 常州大学学生课外科技创新基金暨“挑战杯·卓越”计划资助项目(2014-07-A-21
