摘　　要：文章根据复制式协同产品开发的特点,提出了一种基于隐式特征表达的协同数据交换方法。该方法利用面向对象的特征消息类封装、网络序列化传输以及语义特征重构技术,增量式交换协同操作特征的隐式表达信息,将特征的几何拓扑信息交由接收端系统的建模引擎重构实现。实践证明,该方法极大地减少了网络数据传输,降低了网络传输延时,提高了协同设计的实时性。An implicit feature representation data exchange（IFDE） model is proposed based on the vir- tues of data exchanging for replicated collaborative CAD system. The object-oriented serializable class message encapsulation, serialized internet transmission, semantic feature reconstruction and geometric matching based on dynamic octree technology are used in the model and the geometrical and topologi- cal information of the features are implemented by the modeling engine reconstruction of receiving-end system. It is proved that the presented method can reduce the internet data transmission, decrease the delay of internet transmission and improve the real-timeness of the collaborative design
