摘　　要：1.引言 自从80年代中期CSCW的概念提出以来,在学术界和工业界深受重视,并成为一个迅速发展的新兴研究领域.随着网络技术的快速发展和日常通信和协作的日益频繁,协同工作已经成为不可逆转的潮流,具有广泛的应用前景.This paper introduces a new model for inter-layer message communication called object mapping model that achieves separation between message preparation and destination selection. In this model, as opposed to traditional message delivery model, sender obejcts of messages need not indicate the destination objects of the messages. The messages can be intercepted by special objects called mapper objects. When mapper objects intercept messages, they can decide to which objects the messages should be sent. Using this model,layered cooperative systems can be realized by using objects to construct each layer and using mapper objects to realize object mapping relationship. And object mapping model has many advantages such as modularity ,transparency ,implicit invocation and dynamic mapping.
