摘　　要：计算机支持协同工作(CSCW)操作主要是交互控制、过程控制和并发控制,其中并发控制是至关重要的,因为多个用户共同对共享对象进行并发操作难免会产生冲突,因此从操作对象破坏性和优先级进行考虑,文章给出了一种能够解决冲突的算法,详细描述了该算法的基本思想,设计了并发控制的模型和程序,提出了一种破坏性优先级并发控制策略,实验证明该方法是有效的。Computer supported cooperative work（CSCW） operation mainly includes interactive control, process control and concurrency control, in which concurrency control is crucial, because multiple users who share concurrent operation of the shared object will inevitably lead to conflict. So in view of the destructivity and priority of the operation object, a conflict resolution algorithm is presented, and the basic idea of the algorithm is expounded. A model of concurrency control and its procedures are designed, and a destructive priority concurrency control strategy is presented. Experimental results show that this method is effective.
