In order to meet the requirements of information exchange varieties and manners in wide area protection system, a communication service model based on IEC 61850 is proposed. This service model can realize communication consistency and cooperation between different types of devices. Furthermore, the communication reliability and time delay performance are guaranteed to meet the requirements of relay protection from the upper layer. Message structure of generic sub-station event (GSE) and its communication mechanism are discussed. General methods to communicate digital information by generic substation status event (GSSE) and communicate analog sampling information by sampling analog value (SAV) of GSE are proposed.

With the rapid development of computer technology and network technology, the service model of university library gradually goes to the intelligent, personalized directionfrom the traditional single reference, but there are many shortcomings. It cannot fully satisfy the increasing needs for the division Health research and information, it must actively build the University Library subject Knowledge service model of a science. This paper introduces the subject of service concepts of library knowledge, proposes effective method to build service model of university library knowledge, and strengthens academic knowledge service countermeasures to promote the development of knowledge- disciplinary university library services.

Formal models for service composition have been proposed with the variation of the requirements of service developers. Some famous models have provided checking and verification techniques and tools for the behavior of service composition. These models generally focus much on the message flow of web services and neglecting the data contained in the exchanged messages among services, which restrict the application range of these models and also the web service techniques. As new kind of services with different protocols and communication methods have appeared, it is needed to model service composition from a new view which is adapted to the new development in service area. In this paper we offer a function oriented model of service composition which treats the composite service as a software system and specify the function of services which can be directly used to the realization by service providers.

To make service matchmaking more adaptive to various service requests and diverse web services, an adaptive approach-ASMA is proposed to service matchmaking based on temporal logic model-checking. The approach is based on the proposed abstract service model, ASM-TL, which addresses some important constraints for identifying capabilities of web services, such as service inner constraints and invocation constraints, and also has a virtual process model for describing service behavioral properties. By treating service requests as temporal logic conditions and web services as temporal models, ASMA does service matchmaking through model checking. Therefore, ASMA makes service matchmaking more accurate and more adaptive to the variety of service requests and the diversity of web services. The approach has been applied to the problem solving environment （PSE） for bioinformatics research. Applications show that the approach is suitable for dynamic environments.

The propose of ＂four new＂ economy is to undertake innovation-driven transformation of Shanghai, promote the development of strategic emerging industries and transform and upgrade of manufacturing. In the following years, Shanghai will focus on the capture of key technologies, promoting the transformation of technology, expanding market demand, improving the development of the carrier, encouraging and supporting enterprises, financial institutions and social capital to increase the investment and use of＂four new＂ economy, to promote the ＂four new＂ economy gradually grow and develop. With the ＂four new＂ economy＇s development and growth, its service model should be changed too. On the basis of theory and practice, the text proposes three forms of innovative services models and relate recommendations to promote it.
