For example , if you changed the location of your application server , you could change the file containing the service port without having to update the binding or abstract service interface definition 例如，如果改变了应用服务器的位置，您可以更改包含服务端口的文件，而不必更新绑定或抽象服务接口定义。
An abstract service interface , as described in wsdl , is used to create a layer of abstraction that allows a client written in , say , java programming language , to access a service implemented in , say , c 正如wsdl中描述的那样，抽象服务接口被用于创建一个抽象层，这个抽象层允许（假设）用java编程语言写的客户机来访问（假设）用c + +实现的服务。
This paper proposes and implements the pgs architecture used to separate services and resources , as well as to fulfill the dynamic binding task at runtime , which aims at abstracting services and making full use of various dynamic resources in virtual organization , in order to improve the efficiency of the grid service runtime environment and the qos of services 本文的主要工作是提出并实现了用于分离服务与资源,并进行动态绑定的可接插网格服务体系,旨在进一步抽象服务,充分利用虚拟组织中的各种动态资源,提高网格服务运行环境工作效率和服务质量。
