摘　　要：结合观测结果对中纬电离层暴时形态进行理论模式研究．分析了两次电离层暴变事件中影响其基本形态的原子－分子含量比、上部输运通量和中性风等因素的行为，发现在这两次具有不同特点的事件中,中性风较为平稳，而原子－分子含量比和耦合输运通量的相对作用则各不相同．This paper introduces a new method of the theoretical modeling and simulation of the ionospheric storm behaviour in mid-latitudes, with the use of the experimental ionospheric data. The effects of the atom-molecule ratio, topside fluxes and neutral winds on the ionospheric structure are discssed for the two very different storm events. It is found that, neutral winds vary shadily during the events, while the relativer importance of the ratio is distinct in each event, and the fiuxes differ also. There suggest that the ionosp heric behavioar in the storm time has many dependencies, which can only be determined by the concrete solar-geophysical and atmosphyeric background conditions.
