摘　　要：随着计算机网络技术和分布式理论的发展 ,在异步环境中的时间同步问题就显得越来越重要。提出了一种基于时钟精度差的时间同步策略 ,并给出了相应的证明。同时也讨论了一种基于连续时间变化的领导选择策略 ,以保证获得正确的标准时钟基。As computer network technology and distributed theory have advanced at a fast and steady rate during recent years, the clock synchronization in asynchronous environment becomes more and more important. In this paper, we present clock synchronization policy based on clock precision difference, and give the explanation of this method. At the same time, we also discuss a leader election method based on continuous time changes in order to get a standard time base.
