摘　　要：目前,分布式系统在生活中各个方面的使用越来越广泛,尤其是随着工业控制、军工以及航空航天领域的发展,对时钟同步提出了更高精度的要求。为了满足高精度的要求,首先具体说明了IEEE1588网络时钟同步系统的基本原理,接着通过对IEEE1588网络时钟同步系统的研究,提出了一些可能导致时钟精度下降的影响因素,并做了相应的改进方法。At present,distributed systems are used more and more widely in various aspects of life,especially with the development of industrial control,military industry,and aerospace fields,and the demands for higher precision are imposed on clock synchronization.In order to meet the requirements of high precision,the basic principle of the IEEE1588 network clock synchronization system is first described.Then,by studying the IEEE1588 network clock synchronization system,some influencing factors that may cause the clock accuracy to decrease are proposed,and corresponding improvements are made.
