摘　　要：原子时算法的选用将对原子时标的准确度和稳定度有着很大的影响。本文从AT1实时原子时算法的基本原理出发,结合中国计量科学研究院守时钟房中原子钟的实际情况,对AT1实时原子时算法进行了系统的研究,给出了其算法流程,特别是,对一些关键量进行了分析和数据验证,给出了期望钟组的计算方法,最后得到了期望的钟组计算结果。该结果表明,钟组时间的频率稳定度大大优于每台单个钟的频率稳定度,满足技术要求。Atomic time algorithm plays an important role to the accuracy and stability of atomic time scale. By studying of the principle of AT1 algorithm,and taking the actual research development of the atomic clocks in the timekeeping laboratory of NIM,we present a real time local atomic time AT1 algorithm and bring forward the working flow, The key variables are analyzed and the data is verified in detail. Solution of expectation clock group calculation is given and the computing results are achieved, which indicate that the frequency stability for clock group is＇ much better than every single clock, and can meet the technical satisfaction.
