摘　　要：协同编辑过程实质上就是并发操作的冲突产生与消解过程,有效合理地解决冲突是协同编辑过程的关键问题。首先分析了协同编辑过程中冲突产生的原因,然后对冲突分类汇总,利用时间和参数相关性防止冲突发生,提出了事务日志转存分组策略和事务关联树进行消解冲突,对协同模型重新组合与更新,而且在时间上和空间上不受任何约束,最后通过一个事务建模过程进行应用。经过实验证明,采用日志转存方式保证了协同数据的一致性,很好地解决了协同冲突。Collaborative editing process is essentially concurrent operations of the conflict and digestion process, effective and reasonable solution to the conflict is the key issue of collaborative editing process. First,the causes of conflict in collaborative design process is ana- lyzed, then summary the conflict classification ,use correlation of time and parameters to prevent conflict, and put forward some affairs log dump grouping strategy and affairs associated tree for digestion conflict,fbr collaborative model to combination and renewal,and in time and space without any constraint,finaUy is applied through a process of modeling business. The experiments show that the log dump is to ensure consistency of data together,a good solution to the collaborative conflict.
