Description: Spider又叫WebCrawler或者Robot，是一个沿着链接漫游Web 文档集合的程序。它一般驻留在服务器上，通过给定的一些URL，利用HTTP等标准协议读取相应文档,然后以文档中包括的所有未访问过的URL作为新的起点，继续进行漫游，直到没有满足条件的新URL为止。WebCrawler的主要功能是自动从Internet上的各Web 站点抓取Web文档并从该Web文档中提取一些信息来描述该Web文档,为搜索引擎站点的数据库服务器追加和更新数据提供原始数据,这些数据包括标题、长度、文件建立时间、HTML文件中的各种链接数目等-Spider called WebCrawler or Robot, a collection of documents along the Web link roaming procedures. It generally resides on the server, by giving some of the URL, using HTTP and other standard protocols to read the documentation, then all included in the document URL is not visited as a new starting point, continue to roam until the conditions are not met until the new URL. WebCrawler' s main function is to automatically from the Web site on the Internet crawled Web documents and Web documents from the extraction of some information to describe the Web document, the site for the search engine' s database server and update the data provided additional raw data, including title, length, file creation time, HTML file, the number of various links, etc. Platform: |

Description: 当操作者通过Internet网络控制远端机器人时，结构合理的虚拟操作环境可以增强远程控制能力，
良好的网络通信能力可以保证操作意图的有效性．首先阐明了虚拟操作环境在多机器入网络遥操作系统中
的重要作用，然后分析了以CORBA(公共对象请求中介体系结构)／Java技术融合为基础的中间件技术的特
点，及其在实现分布武虚拟环境过程中的通信作用．在进行虚拟环境(VE)结构分析的基础上，通过定义VE
中的客户类和服务器类，利用统一建模语言(UML)图形化表达了VE框架的内在关系．通过在VE中实现销
孔装配实验，表明通过融合CORBA／IIOP的网络互操作性和Java的可移植对象结构，可以有效实现网络对
象通信；所建立的VE具有良好的人机交互能力，可以保证操作者预期的操作要求和在Internet网络中实现
多操作者实时协作和并行操作能力-When multi-operator control robots through the Internet，logical distributed virtual environment
(DVE)can enhance remote control capability and network communicating capability can guarantee eficient
operations．The importance of VE in an Internet based multiple telerobot system is clarified first and then the
characters of the middleware technology based on CORBA／Java technology is analyzed to realize the DVE．The
definitions of the client class and server class for VE model is built referred to the structural analysis of VE and
the process of teleoperation，and inner connections of system framework and the important application of CORBA／
Java communicating technology is discussed with UML．A pin-in-hole experiment is implemented in VE to
discuss that communication among network objects is eficient by using the interoperation of CORBA and portable
character of Java，and it is also realized that VE in a telerobot system has good interactive capability to
guarantee the operational pr Platform: |
