【Abstract】 In this paper the sample data of earth pulsation are analysed and a combined model is constructed to simulate the data. In the combined model the periodio vibration quantity within low frequence range, randomness and nonstationarity of the data are considered, and nonstationary factor and AR time seriers model are applied.更多还原
