极光

The results show that the electrojet belt is divided by Harang discontinuity into two parts: the minor eastward electrojet in afternoon sector and the major westward electrojet in midnight-morning sector.

研究表明，Harang间断把极光电集流带分为两段：下午—黄昏段的东向电集流带较弱，而晨侧和子夜—凌晨段的西向电集流带较强。

We have to face the tragic fact that came as an exciting aurora leading to the Age of Reason.

我们必须面对的悲惨事实，即是作为一个令人振奋的极光现象，导致了时代原因。

It came as an exciting aurora leading to the Age of Reason.

&它是作为一个令人兴奋的极光导致&理性时代。

It came as an exciting aurora leading to the Age of Reason.

These are Aurora photos taken by Ovar Atli during the winter in Iceland where he had been out at night enduring in freezing cold and often windy nights to take these fascinating shots.

这是所采取的极光照片卵巢Atli在冬季，在冰岛，他已在夜间进行持久的严寒和大风夜往往采取这些迷人的球。

In middle layer of the atmosphere of certain ingredients are decomposed, ionization, composite and other types of photochemical reaction, the occurrence of a variety of luminous phenomena, such as airglow and aurora.

在中间层内，大气中某些成分发生分解、电离、复合及其他各种光化反应，发生各种发光现象，如气辉和极光。

For example, electron- impact- Induced vacuum ultraviolet emissions of atomic oxygen are prominent features in the spectra of Earth's airglow and aurora as well as the atmospheres of other planets such as Mars and Venus.

氧原子的真空紫外辐射引发与电子的碰撞是以大气辉光和极光为特点的，而这种情况与火星和金星非常类似。

Perform global monitoring of airglow, gravity wave and aurora.

进行大气辉光、重力波及极光之全球性观测。

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。

With coordinated EISCAT and ESR radar data, ionospheric storm in both the dayside polar cap and the auroral oval during the major magnetic storm of May 15, 1997 is studied, focusing on the F region negative storm.

联合利用EISCAT和E Svalbard非相干散射雷达数据，研究 1 997年 5月强磁暴期间向阳侧极盖与极光椭圆区电离层F区负暴。

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。
