  ionization recombination
The first and main part of this calculation was setting up and solving the time-dependent equations of ionization/recombination.
      
We find that our observations of the oxygen charge states can be fitted with a single coronal electron temperature in the range of 1.0 to 1.2 MK assuming collisional ionization/recombination equilibrium with an ambient Maxwellian electron gas.
      


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 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.

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(h_0,t)和电子有效损耗率ψ(h_0,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(h_0,t)的日变化、月变化曲线;并发现ψ(h_0,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。

The data observed by EISCAT are used to study the effect of the magnetosphere-ionosphere coupling on the high latitude ionosphere.A case shows that during magnetic storm,even on long summer days,the influence of the magnet ospheric processes on the morphology of the high latitude ionosphere is quite important in comparison with that of the ionization of the solar extreme ultreviolet radiation.The electron density at E-layer significantly increases due to the precipitation of energetic particles from the magnetosphere,while...

The data observed by EISCAT are used to study the effect of the magnetosphere-ionosphere coupling on the high latitude ionosphere.A case shows that during magnetic storm,even on long summer days,the influence of the magnet ospheric processes on the morphology of the high latitude ionosphere is quite important in comparison with that of the ionization of the solar extreme ultreviolet radiation.The electron density at E-layer significantly increases due to the precipitation of energetic particles from the magnetosphere,while the enhancement of the mag-netospheric convection velocity may accelarate recombination of ionization components with neutral atmosphere and cause the nc decreasing at the F-layer altitude.So,usually,ne(E-layer)> ne(F-layer) during magnetic disturbed period.The morphology is not only entirely changed from the quiet period,but also much different in comparison with that at middle and low latitudes.

本文利用EISCAT雷达资料讨论磁层-电离层耦合的高纬电离层效应。研究表明,即使在夏季极昼情况下,磁扰期间的磁层过程对高纬电离层形态的影响也远大于太阳紫外辐射的作用。高能粒子沉降使电离层E层的电子密度大大增加;而磁层对流速度变大会使F层内电离复合加强。因而,磁扰时经常出现n_e(E层)>n_e(F层)的情况。此现象不仅与宁静时完全相反,而且与中低纬电离层形态变化也有很大差别。

In accordance with the experiment results of the tristable phenomena in argon discharge plasma in a double plasma device, the related semiclassical theory based on the fundamental physical processes, such as ionization, recombination, excitation and deexcitation, are established.

本文从粒子间的电离、复合、激发和去激发等基本相互作用出发,解释了实验中观察到的各类三稳现象,并对更为复杂的现象如分岔、混沌等作了讨论。
