摘要

在无扰动条件下，太阳Lyα线发射可以被认为是海拔70 km以上电离层d区电离过程的主要来源。然而，在一些其他能量域的辐射的大的突然影响也可以显著地影响电离率，在本文中，我们提出了一个研究Lyα辐射对电离率的贡献，当电离层受到太阳x耀斑的干扰。利用位于塞尔维亚的VLF接收机采集的数据，对德国DHO发射机发射的VLF无线电信号进行了低电离层的计算和数值模拟。[南斯拉夫]塞族共和国部长项目;3 - 44002, br。[176002 .]176004]

Contribution of solar hydrogen Lyα line emission in total ionization rate in ionospheric D-region during the maximum of solar X-flare

The solar Lyα line emission can be considered as the dominant source of ionization processes in the ionospheric D-region at altitudes above 70 km during unperturbed conditions. However, large sudden impacts of radiation in some other energy domains can also significantly influence the ionization rate and, in this paper, we present a study on the contribution of Lyα radiation to the ionization rate when the ionosphere is disturbed by solar X-flares. We give relevant analytical expressions and make calculations and numerical simulations for the low ionosphere using data collected by the VLF receiver located in Serbia for the VLF radio signal emitted by the DHO transmitter in Germany.
