摘　　要：本文介绍了国际通用的峰下电离层频高图换算方法——POLAN。对武昌电离层垂直观测站(114.35°E,30.57°N)选择了一些典型的时间频高图合成中值频高图后用 POLAN 进行剖面换算,将所得剖面同国际参考电离层 IRI—86给出的密度剖面进行了比较。结果表明,换算所得峰下剖面同 IRI—86计算剖面不完全一致。In this paper,the method of the Polynomical Analysis,POLAN is presented. A comparison is made between the subpeak electron density profiles,obtained at selected local hours by vertical ionosphere sounding at the ionospheric station of Wuchang(114.35°E,29.5°N)and IRI profile for Spring,Summer,Autumn, Winter and one high Solar activity year(1968,R=107).It is demenstrated that the ionospheric profiles above Wuchang do not all agreed with the values from IRI—86。
