In this paper, the dynamic model of predicting the origin time of carthquakcs is established by using the grey control system and choosing 6.0 < Ms < 7.0 seismic sequences from Jan. 1980 to Dec. 1988 inJapan as samples,and the best model is chosen to predict the occurrence of the moderate and strong carthquakcs in Japan. Moreover, in view of function transformation,the model GM(1.1)is interpreted in a broad sense and the model cstablished for the sequence must take time when the smooth degree is satisfied as the starting point.More calculations indicate the at the fitting and extrapolated precisions of model cstablished "enough small number" of samples are better than that by "large number"of samples. This is analysed from the view of information theory.
