摘　　要：Windows 2000的事件传递机制采用了COM+ 松散耦合事件系统，它提供了一种异步信息传递机制，适用于大型多层分布式环境。文章分析了松散耦合事件系统的实现机制，并提出了具体应用模型。Windows 2000 supports COM+ events. It is a COM+ service that extends the COM+ programming model to support late-bound events or method calls between the publisher or subscriber and the event system.COM+ Events is a loosely coupled events system, also refers to as asynchronous message communication. It is adapted in large-scale multi-tier distributed environment.This paper compares LCE with TCE and also gives several application models.
