| Abstract: | Grey system model,quadratic polynomial model and simple polynomial model are used for predicting hydrogen atomic clock error made in Shanghai observatory.The calculating results show that the accuracy of predicting clock error of grey system model and simple polynomial model is equal,which exceeds that by quadratic polynomial model.When the time for data sampling is short,the accuracies of predicting clock error by use of grey system model and simple polynomial model exceed quadratic polynomial model obviou... |
