| 摘要: |
| 本文介绍了在计算机分布式环境下相互合作的进程中通信合作事件间的因果关系（ＣａｕｓａｌＲｅｌａｔｉｏｎｓ），基于在一组相互合作的进程间可能同时服务于多个任务，而且这些任务间可能并不相关这一观点，引入了事件类（ＥｖｅｎｔＣｌａｓｓ）概念，并利用事件类概念，提出了保证因果序（ＣａｕｓａｌＯｒｄｅｒｉｎｇ）的算法． |

| Abstract: |
| This paper introduces the causal relations between events among communicating and cooperating processes in distributed systems. Based on the viewpoint that more than one task may progress among a group of cooperating processes and the tasks may not relate with each other, the authors propose the concept of event class. Furthermore, they propose a causal ordering guaranteeing algorithm using the event class concept. |
| Key words: Process group, communication and cooperation, casual ordering, event class. |
