摘要	The grey system and grey forecast are being increasingly widely used. As we know, a system could be a white system of which all the information can be known, or a black system of which none of the information can be known, or a grey system of which not all the information can be known. An atomic clock is, in fact, a grey system. We can only know the historical information of it, whereas there is some uncertain information for the future. In order to predict the trend of an atomic clock, a linear model or a non-linear model is used frequently, but in this paper a new model named the dynamic grey-autoregressive model is studied. Compared with the older methods, the dominance of the dynamic grey-autoregressive model is discussed in this paper, and finally, the new method is used to forecast the velocity of caesium clocks and hydrogen masers.
