中文摘要：

在 ionospheric short-termforecasting 采用自相关方法，我们提出了一个简单、实际的预报方法-部分自相关方法，也就是说为到四个小时的一个小时的预言向前有“重复”的 RDF 的自相关系数方法被选择，为超过四个小时的预言向前， f_0F_2 与的自相关系数“马上”，方法被使用。预言精确是从重庆和 Guangzhoulonos-onde 车站基于数据估计的份量上。方法很向前为一个小时的预言被改进到四个小时，这被显示出。为超过四个小时的预言，向前，预言错误到达浸透价值，它仍然比“中部”的方法的低。这个新方法能也被用于另外的 ionospheric 参数的短期的预报。

英文摘要：

Adopting the autocorrelation method in the ionospheric short-term forecasting, we put forward a simple and practical forecasting method-- the sectional autocorrelation method, that is, for predictions of one hour to four hours ahead the autocorrelation coefficient of RDF with the ＂iteration＂ method is selected, for prediction of more than four hours ahead, the autocorrelation coefficient of f0F2 with the ＂at once＂ method is used. The prediction precisions have been quantitatively estimated based on the data from Chongqing and Guangzhou Ionosonde Stations. It is shown that the method is much improved for the predictions of one hour to four hours ahead. For the predictions of more than four hours ahead the prediction error reaches a saturation value, which is still lower than that of the ＂median＂ method. This new method could also be applied to the short-term forecasting of other ionospheric parameters.
