摘　　要：普及计算环境中的设备和应用需要通过服务发现来获得其它设备和应用所提供的服务。在服务发现技术中,服务描述、需求描述和服务匹配是迫切需要解决的关键问题。但由于服务和需求的多样性和复杂性,以及普及计算环境的动态性和异构性,使这些问题更加困难和复杂。所以,寻找一种灵活高效而又准确的方式来进行服务描述、需求描述,进而进行服务匹配,具有非常重要的意义。对现有多种服务发现系统中的服务描述需求描述和服务匹配技术进行比较分析,指出了现有解决方案的一些不足,并对未来的研究进行了展望。The devices and applications in pervasive computing environment need to access services of other entities with the aid of service discovery technology. Service description, requirement description and service matching are urgent problems in service discovery technology and are difficult to address because of the diversity and complexity of services and requirements as well as the heterogeneity and instability of pervasive computing environment. To find a way to resolve these problems is of great significance. The article made an analysis to some existing approaches to these oroblems and in the end foresaw the research effort.
