电离层D区域电子浓度和电子有效损耗率随时间的变化

本文根据D电离层的电离复合理论,讨论了利用单站、单一频率的LF天波资料连续监测和研究D区域固定高度上电子浓度N(h₀,t)和电子有效损耗率ψ(h₀,t)随时间变化的方法。应用这一方法对武昌站的部分实验资料作了分析,得到了N(h₀,t)的日变化、月变化曲线;并发现ψ(h₀,t)也有明显的日照效应,上、下午呈现显著的不对称性;两者的逐日变化都较小。 

Variations of the Electron Density and the Effective Electron Loss Rate in the Ionospheric D-region

In the paper it is pointed out that the time variations of the electron density N(h₀, t) and the effective electron loss rate φ(h₀, t) at a certain altitude in D-region may be monitored continuously on the basis of a single frequency LP data obtained at a single station. Some LF data observed at Wuchang Ionospheric Observatory (30°32' 40".64N,114°21'21"32E) are analysed thereby. It is shown that the hourly variations of N(h₀, t) and φ(h₀, t) are asymmetry about noon and the general behaviour of N (h₀, t) are in agreement with the previous published results obtained by other methods. Both the day to day variations of N(h₀, t) and φ(h₀, t) are not obvious.
