Radar altimeters selects full-deramp technology in pulse compression, and apply two frequencies to reduce the ionospheric range errors.

由于现代星载雷达高度计采用了脉冲压缩技术，引入了电离层色散误差，在双频高度计的低频段该误差更明显。

It is found that in both the polar cap and the auroral zone a F1 like peak of ionization appeared at 190km height during the main and recovery phases of the storm; while the normal F2 peak disappeared and great depletions of electron density occurred.

发现在磁暴主相和恢复相初期，极光椭圆和极盖区电离层都在大约 1 90km高度出现类似F1的峰，F2主峰完全消失，F区电子密度大幅度下降。

They experimented with the effects of "artificially induced ionospheric depletions on very low frequency wave lengths, on equatorial plasma instabilities, and on low frequency radio astronomical observations over Roberval, Quebec, Kwajelein, in the Marshall Islands and Hobart, Tasmania" Advanced Space Research, Vo1.8, No.

他们实验&在近赤道离子不稳定区域以甚低频波长人工诱导电离层损耗，或者对魁北克罗伯威尔、马绍尔群岛桂哲林和塔斯马尼亚州霍巴特的低频无线电天文观测&（《高级太空研究》，卷1.8，1号，1988）。

The couplings between the ionosphere and the magnetosphere, thermosphere, and mesosphere as well as the ionospheric processes at different latitudes are key issues today.

It is found that there is a good correlation between ion velocity and Pc 3-5 pulsations.

初步发现：在F层高度上，在P_c3—5频段，电离层离子速度与地磁微脉动H分量有着良好的相关。

It was studied with the aid of a one-dimensional time-dependent ionospheric model self-consistently in the continuity,momentum and energy equations.

通常将地球电离层划分为三个区域，最低的称为D层，依次是E层和F层。

It is shown that seismic activities can arouse the earth-ionosphere cavity resonance anomalies from the observation for many years.

多年来的观测研究表明，地震活动可能引发地球-电离层空腔共振异常。

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 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。
