摘　　要：本文用多年实测数据对 CCIR 第340号报告中给的计算 f_0F1的方法进行了检验,分析了该计算方法产生较大误差的原因是由于未考虑 F1层的磁控效应所致。In this paper in order to evaluate the accuracy of the method of predicting f_0F_1 in CCIR Report 340,we have made a comparison between the f_0F_1 calculated with the CCIR method and a great number of data of f_0F_1 measured in China.We find that there are large deviations at about 20°geomagnetic latitude.The cause is analysed.It arises from the geomagnetic control of the F1 region.A suggestion for improvement has been put forward.
