查询词典 ionosphere

The data of the ionospheric critical frequencies, f0F2 and f0E, observed by a Digisonde Portable Sounder (DPS-4) at Zhongshan station of Antarctica in 1996, the hemispheric power index and the midnight equatorward boundary of the aurora estimated by the observation of American NOAA and DMSP satellites are used to examine features of the polar ionosphere.

本文利用1996年的电离层数字测高仪DPS-4所测的f0F2、f0E以及美国NOAA和DMSP卫星观测估算的半球功率指数和午夜极光区赤道侧边界纬度等资料，考察中山站电离层的极区特征。

Firstly, three popular ionosphere models (Klobuchar model, IRI and JPL GIM) were compared with grid TEC. Then CNC TEC Map using Kriging method with constant drift, linear drift and quadratic drift were compared with each other. Then TEC map derived from nearest neighbor method, polynomial regression method (order=5) and Kriging method with different temporal resolution of 5 minutes, 30 minutes and 120 minutes were compared.

比较了目前被广泛使用的电离层模型（Klobuchar， IRI和JPL GIM）与真实的TEC分布的符合情况；比较了常数漂移（普通Kriging方法）、线性漂移和二次漂移的Kriging方法；在三种不同的时间分辨率（5min， 30min和120min）下，比较了Kriging算法、就近插值算法和多项式回归算法（5阶）绘制CNC TEC Map的效果。

During years of exceptionally high sunspot activity, as was the case in 1990 and 1991, the F-layer of the ionosphere is capable of refracting signals above 54 MHz.

在几年格外高黑点活动期间，象案件1990 年和1991 年，电离层的F 层数是能折射信号在54 兆赫之上。

Detection the Ambiguity slip is key factor for position or attitude estimation of high dynamic SAR satellite using GPS. The ambiguity slip successfully can be detected by ionosphere remanet error of dual frequency.

周跳的检测是高动态卫星利用GPS系统进行定位或姿态测量的关键因素，利用双频电离层残差可以有效地实现周跳检测。

The statistic results showed that: Compared with the earward flow from the midtail, the nearEarth low latitude tailward flow from the ionosphere is characteristic of the lowtemperature and high density; With the tailward flow moving from the lobal region to the plasma sheet, the velocity of the tailward flow decrease, the density and the temperature increase. The tailward flow has distinct anisotropy depending on the difference of the parallel with perpendicular temperature.

对这516起尾向流的统计研究结果显示：（1）尾向流在从等离子体片边界层向等离子体片的运动过程中流速会逐渐减弱、密度逐渐增高，温度有逐渐下降的趋势；（2）对尾向流平行温度和垂直温度的分析显示不同等离子体区域的尾向流都有较明显的各向异性；（3）在从等离子体片边界层向等离子体片的运动过程中，尾向流逐渐趋向各向同性。

Doctor of Physical-Mathematical Science Professor Vladislav Lugovenko of the Institute of Earthly Magnetism, Ionosphere and Radio Wave Emission of the Russian Academy of Sciences met with Boriska and invited him to Moscow for examination.

俄罗斯电离和电磁波放射科学院，物理数学科学家，Vladislav Lugovenko博士，早期地球磁场专家，会见了他。

VHF can also be reflected from clouds of increased ionisation in the E layer of the ionosphere.

VHF 可能并且被反射从增加的电离云彩在电离层的E 层数。

Above the troposphere is the stratosphere, followed by the ionosphere and capped by the exosphere.

因为磁场与线圈内的电流有关，所以电流的任何变化都会引起它周围磁场的变化。

From the surface, the atmosphere is labelled the troposphere for the first 14km up, then the tropopause (4km height), then the stratosphere (about 32km height), then the mesosphere (40km), then the ionosphere (over 600km in height) and finally the exosphere (another 200km), which is the boundary of space.

从表面上看，气氛标签的第一个14公里的对流层上升，那么对流层顶（4公里高度），然后在平流层（约32公里高度），然后中间层（40公里），然后在电离层（高度600公里以上）和最后是散逸层（另200公里），这是空间的边界。

The ionosphere that part of the atmosphere between 65 and 80 km and 280- 320 km height, will be disrupted by mechanical forces caused by the pressure wave following the explosion.

电离层在65-80公里和 280- 320 公里之间高度的大气那一部分，将被随着爆炸产生的冲击波的机械力所扰乱。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
