In this paper the effect of the spatial gradients of the electric field and the neutral wind on the linear growth of the plasma R-T instability and its growth rate are analyzed, based on the quality and the charge conservation equation.

本文从质量和电荷守恒方程出发，分析了控制电离层等离子体R-T不稳定性线性增长的各种因素，重点研究了热层风和背景电场的空间梯度对R-T不稳定性线性增长的影响。

With EISCAT radar observations during 1988～1999, the climatologic features of electron densities in the auroral ionospheric Fregion have been investigated statistically and compared with the IRI2001 model for different seasons at different phases of the solar cycle.

利用1988～1999年欧洲非相干散射EISCAT雷达观测数据，对不同太阳活动周相、不同季节的极光椭圆区电离层F区电子密度进行统计分析，研究其气候学特征，并与IRI2001模式比较。

Climatologic features of the high-latitude ionospheric variatio n with solar cycle, season and local time under geomagnetic quiet conditions are drawn out from the EISCAT and ESR data.

通过分析覆盖一个太阳黑子周期的EISCAT雷达数据(1988-1998)和ESR数据(1997-1998)，得到了平静时高纬电离层F区等离子体参量随地方时，季节，太阳活动周相变化的气候学特征。

It is concluded that conjoint analysis among different parameters should be applied in order to distinguish the precursors related to the earthquakes.

The main idea of this method is: after the double difference ionospheric delay of rover station is eliminated, and other bias relating to frequency of carrier are ignored, the double difference ambiguities are directly searched by only one epoch data using the linear the relation between dual frequencies ambiguities and the integer characteristic of ambiguities.

该方法的主要思想为：当双差电离层延迟误差消除之后，并且忽略其它与频率有关的误差，不解方程组，直接利用模糊度为整数和双频数据之间的线性关系，对流动站的双差整周模糊度进行搜索。

It has also been alleged that the HAARP, or "High Altitude Active Auroral Research Project", which can use the ionosphere as a giant antenna for broadcasting signals, may be used to entrain various mind/body states in large areas of the planet.

也有人指称haarp ，或"高频率活跃极光研究计划"，可利用电离层作为一个广播信号巨型天线，可用于在地球的大范围诱导大脑/身体状态。

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

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。
