Chapter 3 begins with the jabber protocal ’ s message modules and details the jabber three core protocals : message , presence and iq . chapter 4 discusses the design and implementation of the message server . chapter 5 discusses how to implement a mobile client to support mobile users 第三章介绍了jabber的消息模型,并详细分析了jabber的三个核心协议: < message / > 、 < presence / > 、 < iq / > ;第四章给出了消息服务器的设计和实现;第五章设计了一个支持移动用户的移动客户端。
During the wassenaar negotiations , the claims conference signed protocal no . 1 and protocal no . 2 of the luxembourg treaty with the federal republic of germany through coordinating negotiation position with israel . , which not only provided the legal insurance for the world jewish organizations to obtain the reparations from the federal republic of germany but also laid an important legal foundation for the jewish victims to claim the personal compensation from the federal republic of germany 在瓦森纳尔谈判中， “要求赔偿联合会”通过与以色列协调谈判立场，成功地与联邦德国签署了《卢森堡条约》第一议定书和第二议定书，既为世界犹太人组织从联邦德国获得战争赔偿提供了法律保证，也为日后犹太人受害者向联邦德国寻求个人赔偿奠定了重要法律基础。
The key thought of softswitch is to make hardware soft . to realize the function of the swith ' s control , connect and business - processing originally by soft . each entity goes on join and communication through standard protocol . with softswitch it will be faster to realize all kinds of complicated protocal and even more conveniently to offer the business in the business - driving ngn 软交换技术的核心思想是硬件软件化，通过软件的方式来实现原来交换机的控制、接续和业务处理等功能，各实体之间通过标准的协议进行连接和通信，便于在业务驱动的下一代网络中，更快地实现各类复杂的协议及更方便地提供业务。
It also has a series of enhance functions such as : zero position automatic regulation , remote inspect the field control parameter and adjust control parameter pass number locked and so on . at the same time , it can carry though remote parameter enactment , remote control , self - diagnoses etc function by field bus hart protocal 除具有常规智能式的全部功能外，还具有一系列增强的功能,如零点自动调整,远程就地控制参数查看与调整控制参数密码锁定等。同时通过现场总线hart协议,进行远程参数设定远程控制自诊断等功能。

Chapter 2 ananlyses the predominance of conbination of java and xml technologies in development of eai applications , and proposes a data exchange model based xml in eai application . chapter 3 discusses the integration of xml and database , especailly object - oriented database and relational database , and as example , introduces the realization of the transformation betewwn database and xml used xsu . chapter 4 discusses the communication between servers , focuses on xml - rpc and xml messaging , and then introduces simple object access protocal ( soap ) technology and its application in xml - prc and xml messaging 本文共分五章：第1章对eai的概念、内容及应用现状作了分析；第2章分析了java和xml构建eai应用的优势，提出了一个在eai中基于xml的数据交换模型；第3章介绍了数据库与xml的集成，着重是对象数据库和关系数据库，并以xsu为例介绍了其具体实现；第4章讨论了服务器到服务器之间的数据通信，主要是xml远程方法调用技术和xml消息传递模型，重点讨论了简单对象访问协议( soap )及其在xml远程方法调用和xml消息传递中的实现。
The basic principle and technical features of bluetooth technique and protocal stack are introduced and its application area is discussed . the problem in the face of bluetoothe technique are also introduced in this paper . this paper briefly introduces bluetooth sig and bluetooth standard progress . the application profiles and practical applications based on bluetooth technology are given 本文介绍蓝牙技术和蓝牙协议栈的基本原理和技术特点,讨论它现在或将来在各种领域的应用,还介绍了其目前所面临的问题。简述了蓝牙sig和蓝牙标准的进展,给出了蓝牙技术的应用模型和实际应用。
B / s mode is adopted and the realization of functions is assigned between server and browser . several key technologies including transmission protocol , dynamic display technology , collaborative mechanism , collaborative interplay , data transmission protocal , graphics display , data storage , safty and fault tolerance of web - based collaberative are researched . cosuperman , a prototype of web - based collaberative cad / cam system is realized 本文还对基于web的cad cam协同系统开发过程中的若干关键技术进行了研究，主要包括服务器与浏览器的传输协议、模型动态显示、协同机制、协作交互模式、文件存取、安全及容错等，在此基础上用java技术基于acis平台实现了一个基于web的cad cam协同系统原型? cosuperman 。
Group signature is one of the useful singnatures , by now , in all the schemes , acjt is the best in all kinds of capabilities , as it satisfies the common security requirements , at the same time , it resisits all the attack ways . this paper reviews the requirements in special setting , then provides 3 types of group signature . firstly , in the electronic commerce , it needs the anonymity , when one use the electronic coin , he could not be tracing , blind signature can satisfy the security requirement , and group signature is often used in electronic bank scheme , so group blind signature can satisfy all these security requirements . with the protocal of blind bidiscrete logarithm proposed by l . anna and r . zulfikar , this paper implements the group blind signature on the acjt scheme 首先,在电子商务等实际应用场合中,需要保持匿名性,即任何人使用电子货币后,不能被跟踪,盲签名可以满足这种安全属性,而群签名又常常用在电子银行的实现方案中,因此群盲签名可以满足这两个需求,因此本文在l . anna和r . zulfikar提出的一个盲化的双离散对数协议的基础上,基于acjt方案实现了群盲签名。
