浅谈梨尾寨隧道涌水突泥处理施工技术

随着当前我国经济的快速发展,在长途运输方面,顺畅的交通可以促进经济的发展。因此,公路建设是我国经济发展的基础。在偏远的山区,公路的修建是重点也是难点,山区的自然条件决定了山区高速公路的建设要比平原地区复杂的多。隧道建设是山区公路建设的重点。介绍梨尾寨隧道涌水突泥及塌方的处理工艺,包括原因分析、处理方案及处理后的开挖支护、二衬施工及施工中的注意事项。     

Stokes 方程的压力梯度局部投影稳定化方法

作者将压力梯度投影方法和宏元剖分相结合,对Stokes 方程提出了一种新的局部稳定化方法,该方法的稳定项只与压力梯度投影和宏元内部边界跳跃有关,而且不需要修改右端,实现起来更容易.     

Land potential appraisal for urban land reserve based on GIS：

With the rapid urbanization, land banking has become an important means for rational land use and land configuration optimizing. Rational urban land reserve and supply plan are keys for an urban land banking. GIS has been used to model urban growth, growth at the ruralurban fringe specifically. This paper identifies that the urban land banking potential can be evaluated based on RS and GIS technology. 10 indicators were chosen in the integrated index system. As a case of Metropolitan area in Chongqing, urban land banking potential was evaluated based on RS and GIS technology. With GIS, two steps can help to finish potential analysis of land banking. One is goal driven process, such as the process of planning and definition; the other step is datadriven process, such as the process of Manipulating. The results are used to establish the current land banking plan.      

AOP event manager in open service gateway 〖WT5"HZ〗Abstract:〖WT5"BZ〗 〖WT5”HZ〗Key words:〖WT5”BZ〗

The Open Service Gateway Initiative (OSGi) has played an important role in ubiquitous environments that support interoperability among embedded devices, such as home appliances and network devices. However, the OSGi does not have a common event mechanism yet, and it is difficult to communicate among services asynchronously. In the present work, a common event manager, AspectOriented Event Manager (AOEM), was designed on an OSGi framework. AOEM supports services to generate and provide notification of events. This paper presents the implementation of AOEM as an OSGi bundle with AspectJ. The experiment on transferring between device service and application service demonstrate that AOEM provides good abstraction of the services and convenience.     

游鹞子寨

那天上午，我们告别游人如织的金鞭溪，从千里相会景点出发，沿山中一条依山就势蜿蜒曲折的游道拾级而上。这条游道有些落寞，路上长出了青苔，散落着枯叶。看得出来，鹞子寨的这条上山游道几近荒芜，人迹罕至。不过我很喜欢这样的游道，非常原始生态，特别闲适幽静，没有繁华都市的喧嚣，没有热闹景点的浮躁，一个人可以自主地行走，或者漫步沉思，或者一路轻歌，什么都能想象，又什么都可不想。     

20世纪20年代以来的东北少数民族村寨研究

对20世纪20年代乡村社区研究兴起以来涉及到东北地区少数民族村寨的学术活动和研究成果进行了简单梳理,认为东北地区少数民族村寨的研究过程可分为三个阶段,分别是20世纪20年代至40年代的起步阶段,50年代至70年代的发展阶段以及80年代至今的繁荣阶段。在论述各阶段研究特点的基础上,提出东北地区少数民族村寨的后续研究需要研究者有效兼顾民族志书写和理论剖析两个方面,从而实现对研究对象更为全面、客观、理性的认识和探究。     

罗家伦的新疆行及其《西北行吟》

20世纪40年代,罗家伦先后以西北建设考察团团长、新疆省监察使的身份考察和驻节新疆。公职之余,写过一百多首有关新疆的诗歌,后编入《西北行吟》存世。这些诗歌力求达到历史真实与现实生活真实的结合,多姿多彩的自然样态与人文社会样态的结合,抒写深度与广度在民国时期新疆汉语文学史上并不多见,也是对同时期国人的新疆想象与描述的某种超越。其诗风多样,尤擅雄奇阔大一路,具有一定成就。

Grid GIS and its application in digital city

Digital city is a synthetic project in which large geographic and trade data are involved in, thus data sharing becomes a key problem. Grid GIS is an outcome of integrating GIS and network techniques, it has a lot of characteristic of network technique such as heterogeneous, extensible, dynamic autoadaptable, the multistage management, etc. The advantages of parallel processing of grid computing are obvious when it is used in basic data platform construction of digital city. The architecture and core techniques of Grid GIS which suitable for constructing basic data platform of digital city was discussed, it has some guidance effects to the city information building.      

A novel architecture for cargos location and safety in networked RFID

Using Networked RFID equipped in warehouse or supermarket distribution, Enterprise information system (EIS) can gather and deal with cargos information. Nevertheless, when cargos are in traffic, the Networked RFID can't monitor the cargos any more as the products tagged aren't within range of a reader. This paper proposes a solution framework which combines Networked RFID and GPS tracking, and then equip with this system in container to make the cargos monitored even if the cargos are in traffic. This solution can solve the accurate consignments, position tracking and advanced theft happening through drilling holes in container. In addition, customhouse and checkpoint can get an electronic shipment manifest rapidly and safely when a vehicle gets through a checkpoint.
