摘　　要：协同CAD系统中的操作意愿保证是一个复杂而又关键的问题 ,其研究具有挑战性。首先分析了图形对象的并发操作的特点和冲突 ,给出了一个全新的对象标记模型 ,解决了非几何和删除类操作的冲突问题 ,与对象复制算法一起构成一个通用模型。基于该模型 ,对一些相关算法的实现 。The operational intention pledge of collaborative CAD system is a complicated and crucial issue, its study possesses a challenging character. The characteristics and conflicts of concurrent opteration of figure object are being firstly analyzed, an entirely new model of object mark is presented. The issue of non-geometric conflict and conflict of deletion operation is solved, and it constitutes a general model together with the algorithm of object replication. Based on this model, a deepgoing discussion is carried out on the realization of a few related algorithms.
