Net technology and XML technology, and then designs and implements the reporting system.

Net和XML技术，提出了基于XML的可复用报表生成系统的概念，设计并实现了报表生成系统。

S is a XML based technology, which is designed to help the isomerous systems to communicate with each other easily. With the help of XML, data can be transfered between procedures written by different languages.

eb服务技术是用来解决异构网络程序之间的交互问题的，它采用XML(eXtensible Markup Language，可扩展标签语言)来保证在不同平台上，不同语言编写的程序之间可以以统一的方式相互调用。

Hence, it is an important challenge to develop efficient and scalable methods for XML data mining.

因此，开发出有效的针对XML的数据挖掘方法成为数据挖掘领域和XML技术领域的一项重要课题。

This is because XML language can store the data , similar to the function of the database .

XML , or Extensible Markup Language , is written in Standard Generalized Markup Language and essentially allows you to define your own markup language.

XML ，或者可扩展的标记语言，是用标准通用标记语言所写的而且可以允许你来定义你自己的标记语言。XML在因特网上描述，分享，和输送数据很有用。

Inherited from SGML (Standard Generalized Markup Language), XML (Extensible Markup Language') has the characteristics of flexibility, extensibility and simpleness.

XML作为下一代Internet语言，具有极大的灵活性。利用XML，可以在Internet展开各种复杂的应用。

According to the difference of data types, XML and UDO as data storage methods are used separately. The establishment of XML for data, such as edit, deletion, etc is achieved. With the system requirements, it needs not only local data operation, but also network communications.

根据协同设计中的数据类型的不同，分别采用可扩展标记语言和用户自定义对象作为数据存储方式，实现了数据的存储，实现了在XML中对数据的创建，修改等编辑操作。

Primarily, the thesis assays the condition of network framework, the network was divided into three levels in terms of network management in order to establish the distributed method ,and still pointing out the intention and denotation of studying the Topology Discovery.Next, the thesis analyzes SNMP protocol minutely, including its development, principle, and the Network Management system that established on the SNMP protocol. Have analysed MIB in detail and the application way of MIB in network management .The thesis also assays the ICMP protocol, describing its working principle and the format of datagram minutely , and describing two important tools of ICMP- Ping and TraceRoute in detail. On the base of upper analysis, the thesis expounds a kind of distributed Topology Discovery project, and book it in one autonomy system. Topology Discovery was divided into two levels in terms of network management, and analyses the way of linking up between the two level. The thesis minutely assays Router-Level Topology Discovery technology basing on SNMP and Subnet-Level Topology Discovery technology basing on ARP and ICMP. According to these analyses, the thesis explores the specific methodology and the technology of XML data object which using the WinSNMP API to achieve topology discovering system on the development platform of Visual C++, and also analyses the technology of topology analysis and topology graph minutely. Moreover, the thesis assays the technology of basic firewall and Topology Discovery response strategy. Finally, the thesis analyses the underlying blind problem of the topology finding, and also analyses the reason that the blind problem produced and the way that reduced. The distributed algorithm that this paper puts forward has a certain directive significance in wireless network or other fields.

本文首先分析了网络结构状况，将网络从网络管理的角度划分为三个层次，为分布式的方法奠定了基础，同时还指出拓扑发现研究的目的及意义；接着本文分析了SNMP协议，详细分析了SNMP协议的发展状况，协议的工作原理，以及由SNMP协议基础上建立的SNMP网络管理体系，详细分析了MIB，以及MIB在网络管理上的应用方式；本文又分析了ICMP协议，详细描述了ICMP的工作原理和数据报格式，并详细描述了ICMP的两个重要工具-Ping 和TraceRoute；然后本文在结合上述分析的基础上，提出了一种分布式的拓扑发现方案，将拓扑发现拟订在一个自治系统内，将拓扑发现从网络管理角度划分为路由器级和子网级两个层次，分析了两个层次之间的衔接方式，同时从拓扑地域的角度将拓扑发现过程分布化，分析了分布式算法的具体方法和分布式结点之间的数据通讯方法，本文详细分析了基于SNMP的路由器级拓扑发现技术和基于ARP和ICMP的子网级拓扑发现技术；根据这些分析，本文利用XML数据对象作为分布式算法中的数据对象，分析了XML的技术，本文使用Visual C++开发平台实现网络拓扑发现系统，详细分析了使用WinSNMP API实现基于SNMP的路由器级拓扑发现和基于ARP的子网级拓扑发现，分析了使用Winsock编程实现基于ICMP的子网级拓扑发现，本文还对拓扑分析和拓扑图的绘制技术作了较细致的分析；本文最后还分析了基本防火墙技术，分析了几种类型的防火墙对拓扑发现带来的影响，以及在拓扑发现时的应对策略，本文还分析了拓扑发现中可能产生的盲点问题，分析了盲点产生的原因以及拓扑发现中减少盲点的方法。

There is great difference between the data structure of XML and the data storage structure of database, and XML technology is not only unripe, but also discommodiousness.

但由于XML表示数据的结构和数据库存储数据的结构存在很大的差异，这种技术不成熟，而且使用也不方便。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.
