摘　　要：利用亚洲、澳大利亚地区8个电离层观测台站的F_2层临界频率f_0F_2的历史观测数据,考察了NeQuick模式预报电离层基本参数f_0F_2在亚太扇区的适应性.对比分析表明,此模式能比较好地预测各地的F_2层临界频率,其绝对误差在南半球各站相对北半球各站较大,太阳活动高年相对太阳活动低年较大,春秋季相对夏冬季较大.其误差均方根在太阳活动高年相对太阳活动低年较大.In this paper, with the observed critical frequencies of F2 layer at eight ionospheric observatories in Asia-Australic sector, the prediction ability of the NeQuick model on f0F2 over Asia-Australic sector were investigated. The agreement between the prediction by the NeQuick model and the observed f0F2 data in this sector is quite satisfactory. The model prediction error is bigger in the northern hemisphere than in the southern hemisphere, bigger in the years with high solar activity than in those with low solar activity, and in spring and autumn than in winter and summer. The RMSE is bigger in the years with high solar activity than in those with low solar activity.
