In this paper, in terms of diffusion equation of neutral gas in thermosphere and main ion-chemistry reactions in ionospheric F region, the diffusion processes of H2, H2O and CO2 and ionospheric response to released gases are investigated.

根据中性气体在热层背景中的扩散方程，考虑电离层F区主要的离子化学反应，研究了H2，H2O和CO2气体在电离层高度上的扩散过程和电离层对所释放气体的响应，计算了气辉的体发射系数和发射强度。
