| 摘 要： | 时间序列分析在变形数据处理及预测上具有一定的精度，但无法探测到序列隐含的周期性变形因素，具有一定局限性。在时间序列分析方法的基础上，在数据预处理部分添加了频谱分析的方法，对数据进行进一步处理和预测，结果表明：结合了频谱分析方法的时间序列模型在数据的处理和预测方面能够进一步提高精度。

| Abstract: | The time series analysis is of a certain precision in data processing and forecast, but it can not distinguish the seasonal deformation factors hidden in the time series. Here, the spectral analysis method is introduced into the data pre- processing so as to make the further processing and forecast. The result shows that the combination of the time series analysis and spectral analysis can further improve the accuracy of the deformation processing and forecast. |
