13334 就磁暴期间Bz分量和Dst指数的观测值来说,2004年11月的磁暴事件最强,其次是1月的,2月的最弱。 In terms of Bz component and Dst observation, the strength of geomagnetic storm in November is the strongest, followed by it in January, and the geomagnetic storm in February is the weakest.
13335 而地基闪烁监测仪的观测结果表明:1月磁暴事件期间,L波段电离层闪烁最强,闪烁指数S4最大值接近于1.0,闪烁出现率的最大值超过80%。 However, the observations from the ISM show that, the L-band ionosphere scintillation is strongest during the January geomagnetic storm, the peak S4 value and peak scintillation occurrence is close to 1.0 and 80%, respectively.
13336 2月磁暴事件期间,电离层闪烁持续时间最长,S4最大值接近于1.0,闪烁出现率的最大值接近63%。 The duration of ionospheric scintillation is the longest during the February geomagnetic storm, with the peak S4 value and scintillation occurrence close to 1.0 and 63%, respectively.
13337 11月磁暴主相和恢复相期间,无电离层闪烁现象出现。 During the main phase and recovery phase of the November magnetic storm,there is no ionospheric scintillation.
13338 CHAMP卫星和地面闪烁监测仪观测到的结果一致,表明多重尺度的电离层不均匀体通常同时存在,但是小尺度的电离层不规则体通常会先消失。 The observation derived from CHAMP satellite is in consistent with that from ISM. The results show that the large scale ionospheric irregularities tend to appear when the small scale irregularities are present, but the small scale ionospheric irregularities usually disappear first.
13339 对比上述三次实验的观测结果,我们推断造成电离层响应特征差异的原因与环电流的影响有关，Aarons准则可较好地解释电离层对3次磁暴事件的响应。 We conclude that the differences in the response of ionospheric are mainly related to the effect of ring current,which could be well explained by Aarons' criterion.
13340 同时跨赤道风场可能也有贡献,它通过增加沿场向积分的Pedersen电导率。 The neutral wind may also have contributions to these differences.
13341 针对高空核电磁脉冲(high altitude electromagnetic pulse, HEMP)试验研究,分析了电小环天线测量原理和频率特性,建立了传感器数值模型,研究了其脉冲接收特性。 For the high altitude electromagnetic pulse testing research purpose, the measuring principle and frequency characteristic of electrically small loops are analyzed in this paper. A numerical model of electrically small loop is founded, and the pulse receiving characteristics are obtained by simulation.
13342 设计了一种B-dot传感器,研制了一套脉冲磁场测量系统。 Then, the B-dot sensor is designed, and a pulsed magnetic field measuring system is constructed.
13343 结果表明：当环面半径小于20 mm,传感器的上限截止频率达到720 MHz以上,标定结果显示测量系统整机的上升时间小于1 ns。 The results show that the sensor's upper cut-off frequency exceeds 720 MHz when the ring radius is less than 20 mm, and the system calibrated risetime is less than 1 ns.
