Therefore, the observation of Na layer is one of the important method to study the dynamical process in the mesopause region. In this paper, we combine a timedependent photochemical model, the International Reference Ionosphere model (IRI95) and a photochemical model of sodium to develop a time dependent sodium photochemical model.

本文建立了时变的中高层大气光化学模式，并与国际电离层模式(IRI95)与Na层光化学理论相结合，建立完整时变的中高层大气Na层光化学模式，着重研究Na层分布的昼夜变化。

The Kamide-Richmond-Matsushita magnetogram-inversion algorithm is used to study the electrodynamic features of auroral electrojets. It is concluded that there is also two components in the westward electrojet in the midnight sector, i.e., electric field-driven and conductivity-driven components.

利用Y.Kamide等发展起来的地磁反演电离层电磁学量方法，研究了极区电激流电动力学特性，结果表明子夜附近西向电激流也可由两部份组成，即分别由电场驱动和电导率驱动。

The distributions and variations of the convection electric field,the region l and region 2 field aligned currents, the ionospheric disturbance current system including the auroral electrojet,and ionospheric conductivity all together compose a self consistent organic whole.

对流电场、一区和二区场向电流、电离层扰动电流系，以及电导率的分布和变化乃是一有机整体，对其每一环节的深入认识均与对整体的全面了解密不可分。

According to the different scattering medium, scattering communication are generally divided into tropospheric scatter communications and ionospheric scatter communication.

根据散射媒质的不同，散射通信一般分为对流层散射通信和电离层散射通信。

The credibility gap is the result of a deliberate policy of artificial manipulation of official news.

民众对政府的不信任是官方假造新闻政策的结果。火箭和人造卫星能够到达电离层以上极远的地方。

The reaction emitted a 6300 A airglow. Between 1975 and 1981 NASA and the US Military began to design ways to test this new phenomena through deliberate experimentation with the ionosphere.

这一相互作用发出 6300 A气辉。1975到1981年间国家宇航局和美国军方开始设计通过对电离层的有意实验来测试这一新现象的方法。

However, when pressed most would admit that the ionosphere must have been weakened at the time, so that the electrically charged particle hitting the earth's atmosphere created the highly visible light called airglow.

然而，当被施加压力之后大多数人会承认电离层一定是在那个时候被弱化了，以致于带电粒子撞击了大气产生了称为气辉的高可见光。

Some of the examples in her book include the Tang Shan earthquake in China, which occurred on 28 July 1976, and left 650,000 people dead. The catastrophic event was preceded by an airglow, said to have been caused by Soviet ELF wave experiments to heat the ionosphere.

在其书中举出了一些例子，其中包括1976年7月28号发生的中国唐山大地震，剥夺了六十五万人的生命，但在这灾难发生之前有大气辉光现象，据说是苏联极低频电磁波试验加热电离层导致了这一惨烈的灾难发生。

Airglow and aurora are important optical phenomena. Their radiation, especially ultraviolet radiation contains fundamental chemical and physical information about upper atmosphere and ionosphere.

气辉和极光是高层大气中的重要发光现象，其辐射特性、特别是紫外波段的辐射特性，是高层大气和电离层物理化学过程信息的重要来源。

Additionally, airglow volume emission rates and intensity from the release at ionospheric altitudes are calculated The results show that the diffusion of released neutral gas in F region is very quick, and these gas molecules can cause a large-scale depletion of ionospheric electron density.

结果表明，中性气体在电离层高度上扩散非常迅速，在F区的一些高度上，主要正离子成分由O转变为其他分子离子，且在释放过程中伴随气辉发射，发射气辉的波长和特征与释放物质的种类有关。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
