Abstract: The atomic time scale is the reference for the master clock frequency sources in time keeping laboratories around the world.Since most time-keeping laboratories are equipped with only a single type of atomic clock，a single time-scale calculation method can achieve good results.With the development of multiple types of atomic clocks in our country，using a single time scale calculation method will not give full play to the performance advantages of different types of atomic clocks.In order to calculate the time scale more reasonably，we propose to choose different time scale algorithms for different clock ensemble configurations.The characteristics of hydrogen masers and cesium atomic clocks are analyzed，including long and short term fluctuation，frequency stability and frequency drift.Then，we propose an ALGOS-LIKE algorithm，based on the two types of atomic clocks，the ALGOS-LIKE and AT1 time scale algorithms are used to calculate,compare and analyze.The results show that i) under the configuration of the cesium atomic clock ensemble，the time scales generated by the AT1 algorithm are of the order of E-14 for hour and E-15 for 5 days，and the long-term and short-term frequency stability are better than the calculation output of the dynamic ALGOS-LIKE algorithm;ii)under the clock ensemble configuration of the hydrogen maser ensemble，the ALGOS-LIKE algorithm is better，and the long-term frequency stability is improved compared with the AT1 time scale algorithm.
