| 摘 要： | 本文给出一个从电离层频高图提取F1-F2谷区信息的剖面分析方法.利用该方法分析处理了武昌站的垂测记录,揭示了我国中低纬地区上空F1-F2谷区形态的某些变化规律和地区特色.对该类谷区的形成机制进行了初步探讨,认为在光化理论中若考虑基态与亚稳态两种氧离子的不同作用,可以说明该谷区的出现和基本变化趋势.

| Abstract: | The paper describes a profile analysis procedure to extract the information of the F1-F2 valley from ionograms. Through the reduction for a number of observed records at Wuchang, a lower mid-latitude station in China, some new features of the morphological regularities of the F1-F2 valley art revealed. It is indicated that the formation and development of the valley in the F region can be interpreted by some numerical calculation on the basis of the photochemical theory, if the effects of both O+ (4S) and O+(2D) are taken into account. |
