| 当今的计算机软件变得越来越庞大，它们所提供的服务（即功能、命令、操作以及资源等的总称）越来越多、越来越全，通常，用户对服务的请求是以“选择－执行”模式（或类似的模式）进行的，其中“选择”是指指定服务（无论是用名字指定，还是通过击鼠标钮激活图标来指定），而“执行”是指服务自身的运行。这种“选择－执行”模式使得服务处于一种被动的地位，即如果用户不知道如何请求某服务或根本不知道服务的存在，则此服务也许就永远被撂置一边了，这种被动性服务有许多不足。本文提出一种新的观点，即主动性服务观点，这一观点的基本思想是：在一 |

| Abstract: |
| Software of today becomes more and more large, and it provides more and more services. Usually, the“selection-execution”model is used to invoke available services of a software. Therefore, there may be many services in a software which have never been invoked by its users, or whose existence is unknown to its users. This paper introduces a notion called active services. An active service is a service which can invoke itself under some circumstances, although its users may not know its existence. It also presents three basic models of active services and demonstrates their applications in various software. |
| Key words: Service active service selection-execution. |
