摘　　要：本文分析了国际原子时的概念、实现方法、性能要求，总结了主要的地方原子时系统的基本情况，重点分析了中、美、俄等国家原子时系统特点，统计分析了各地方时频系统在国际原子时计算中的权重比例，分析了国际原子时与UTC、GPST、BDT等其他时间系统的关系，为原子时的系统实现和应用提供参考。The concept, realization analysis and capability requirements of international atomic time are analyzed. The basic information of the main local atomic time system are summarized. Especially, the atomic time systems of China, U. S. , and Russia are described in detail. The weights of various time laboratories in international atomic time computaion are shown statistically. The time relations between TAI and UTC, GPST, BDT, etc. are analyzed . The papaer can be referred by atomic time system design and applications.
