| | This paper presents the results of correlation analysis between the data of energetic particle pulses obtained by IMP-J spacecraft (P4: 230keV>.E>160keV) and auroral electrojet index AE. The magnetotail is devided into three regions: neutral sheet region, low latitude region and high latitude region. It is found that: (1) In the neutral sheet region, the average energetic particle fluxes is the highest among all three regions. In the high latitude region the fluxes is the lowest. This indicates that the "so... | | 利用行星际监察卫星IMP-J取得的高能粒子探测数据(质子能档P4:230 keV>E>160keV)与极光电激流指数AE作相关分析,在地心太阳磁层坐标下,按照Fairfield关于中性片对地心太阳磁层“赤道面”的偏离模式,把磁尾分成三个区域:中性片区域、低纬区域和高纬区域.结果表明:(1)高能粒子脉冲的平均强度在中性片区域最强,低纬次之,高纬最弱,表明高能粒子脉冲源区在中性片区域;(2)中性片附近,粒子脉冲和AE指数相关最好,达0.59,低纬次之,高纬几乎无相关,表明粒子脉冲与亚暴事件有关,它是磁尾中性片附近磁力线重联产生的感应电场加速的结果;(3)粒子加速区局限于中性片附近的薄层内,与国外结果完全一致. | | 文摘来源 | | This research work was carried out in Dosso's laboratory at the Department of Physics, University of Victoria. Besides coastlines, the Hainan Island region is also composedof several typical features, such as the big shallow bay, the narrow shallow Channel, thebig island and the seamount surrounded by deep ocean. The understanding of theelectromagnetic induction anomaly of these features will benefit not only the globalgeophysics but also the exploration geophysics. The contour plots and three-dimensionalvi... | | 本文的研究是在加拿大维多利亚大学物理系Dosso教授的实验室里进行的。海南岛地区包括有除海岸外的其它几种典型的海陆结构。如海湾、海峡、海岛及海山等。对这些结构的电磁感应异常的认识不仅有益于全球地球物理研究,对地球物理勘探亦有指导意义。根据模型测量资料绘出的三维场量图和等值线图直观地显示了整个模型上场量的空间分布,特别是突出表现了各场量在海岸、海块、海岛及海山附近的异常特征。同时,还进行了视电阻率和感应传输函数的计算,分析了不同结构电磁响应的频率特性。该模型实验首次详细地揭示了海山型结构的电磁响应特征。海山响应在某一频率出现同相分量的极大值,且该极大值对应着异相分量的过零点。出现极大值处的频率称为最佳频率,研究最佳频率随上覆层电阻率、层厚及海山几何尺寸变化的关系,将有助于二维构造的解释。实验结果还表明,上地幔高导层对地面观测场的影响表现为对各场量的衰减,同时使频率特性发生偏移。在地表为高导层时,上地幔高导层的影响减弱,该特性称之为高导层的屏蔽作用。 | | 文摘来源 | | In this paper, a storm model is presented taking the magnetic field ecolution of a coronal active region as the driving force of the noise storm phenomena. And it has been assumed that a coronal active region is inhomogeneous in magnetics, there are" strong magnetic field fibers in it. The evolution of the magneic structure of an active region will produce weak shocks. When the shocks pass a coronal arch, a fraction of electrons is heated. The, heated fast electrons form a local loss-cone distribution in st... | | 本文以日冕活动区磁结构演化为噪暴现象的驱动力,并假定日冕活动区在磁学上是不均匀的——存在强磁场纤维,提出了太阳米波噪暴的哨声模式.活动区磁结构的演化将在冕弧中产生弱激波.当弱激波通过强磁场纤维时,加热部分电子,被加热的电子在强磁场纤维中形成损失锥分布.在日冕的噪暴区域中,快速电子的损失锥分布将产生高亮度的哨声波和朗缪尔波.通过感应散射,朗缪尔波滑向低波区域时将与哨声波发生强烈的互作用而产生窄束电磁辐射(Ⅰ型爆发).强磁场纤维及相应的场位形决定了Ⅰ型爆发的频宽和持续时间.而噪暴连续谱则采用通常认为的各同向电子产生的朗缪尔波与低频波耦合的产物. | | 文摘来源 | |   | | << 更多相关文摘 |
