莫莫格湿地干-湿界面优势植物种群动态分析

莫莫格湿地从高河漫滩底端到顶端选取有代表性的植物群落片断作为固定观测样带,并设置6个观测样方,生长季5月、7月、9月3次观测结果表明,小叶章优势种群5月份密度最高达1154-1594株/平方米,7月种群数量下降,9月有所升高;踏头苔草优势种群5-7月份密度在3 414-7 193株/平方米,9月份种群数量大幅度下降;土壤相对含水量低地段小叶章种群相对优势度大,土壤相对含水量高地段踏头苔草种群相对优势度大,局部地段生长季内有相对优势度相互替代过程,莫莫格湿地干-湿界面上小叶章和踏头苔草两个种群可以共存。     

RFID阅读器的驱动及模块设计

当前，大部分有关RFID的文章，都在探讨RFID在提高产品物流速度和信息采集质量方面的作用或研究有关RFID硬件设备，而有关RFID阅读器的驱动及接口技术方面的研究很少。主要介绍了RFID阅读器的驱动模块及模块工作原理，同时介绍阅读器与上层数据管理器之间的接口设计。     

Target-based Security Management Architecture Applied to Management Information System

In order to implement the security management of management information system (MIS), a target-based security management architecture is proposed. For MIS users, the user interface (UI) is the only way to interact with the MIS system, so all the objects (targets) which need to be managed on UI is registered first, thus for every target the state such as enabled, not enabled, visible, not visible, readonly etc., is assigned. For some users, a set of targets with some state is assigned so that the management granularity in MIS can reach any degree. This approach provides a very flexible way to the security management in MIS.     

The Unified Representation of Interface Conditionsof Electromagnetic Quantities Using Exterior Differential Forms

A continuity condition of p-forms across a p-dimensional submanifold isderived.The,various interface conditions of electromagnetic quantities are obtained through theapplication of the continuity condition to Minkowski manifold of space-time.     

Internet Telerobotics and Its Applications

According to a new trend of telerobot control, some key techniues are researched to solve the Internet telerobotics , such as distributed intelligent computation on the Internet, human-computer interface,and Internet-robot interface etc.The current development status of the Internet telerobotics is reviewed. Based on the new directions of the network software development, the authors discuss that the middleware technique CORBA plays an important role in solving the problems of the Internet telerobotics,and it is an effective way to use Java language to control the telerobot and improve its system performance. The application perspective of the Internet telerobotics is investigated.It is indicated that the development trend of the telerobot control is a human-centred collaboration mechanism of mutual reinforce and coordination in human-machine intelligent.
