摘　　要：提出了一个基于事件流和组件的CSCW开发平台设计方案，并以此构建了Beacon 系统，它支持组件化的开发模式，以事件流处理为核心，全面覆盖了从网络通信、群组通信 、访问控制到并发控制等多个环节，并在对象交互模型、事件处理和并发控制策略方面有所 创新。通过在Beacon系统上开发了几个协同应用程序，验证了该平台具有很强的扩展性、通 用性、稳定性和开发灵活性。A general CSCW development platform——Beacon system is presented ba sed on the event flow and component methods, which supports component-based deve loping modes, dealing with the problems involved in network communication, group communication, access management, concurrent management, etc. The system takes a new sight in building the model of objects interoperation, the method of even t disposal and the scheme of concurrent control. By developing several cooperati on applications on top of Beacon system, it is proven that the system has a stro ng extensibility, generality, stability and flexibility.
