摘　　要：文章以白板工具SWT的设计为背景,在对群体交互操作过程中引起冲突的原因进行分析的基础上,提出了一个并发控制算法,用于协调群体交互过程中操作的冲突问题。该算法采取基于“操作语义”原则的冲突检测方案和仅对已执行冲突操作事件进行修正策略,具有响应时间快以及控制灵活等特点。The paper puts the whiteboard tool SWT as a background.A concurrency control algorithm is provided based on the analysis of the reason casuing confliction during group memebr cooperative operation.Its mainly task is to coor-dinate the confliction.The algorithm has the characteristicss such as a short response time and control flexibility,be-cause it adopts the conflict detection principles based on″operational semantics″and strategies only modify on the op-erational event which executed existing confliction.
