地球磁鞘中磁场起伏特性的分布

They may play an important role in the interaction of the magnetosheath plasma with the magnetopause .

它们在磁鞘等离子体和磁层顶的相互作用过程中可能起很重要的作用。

The anisotropy of plasma pressure in the magnetosheath has strong influence on the generation of the K-H instability .

各向异性对K-H不稳定性有显著影响。

The physical processes described above may be useful in understanding the anomalous transport phenomena of energy and momentum from the magnetosheath to the magnetosphere .

上述物理过程可能对解释磁鞘至磁层的能量及动量异常输运现象有所帮助。

The main results are : ( 1 ) the fluctuation intensity and fluctuation anisotropy of the interplanetary magnetic field are amplified obviously in the magnetosheath region ;

主要结果是：（1）行星际磁场起伏的强度和各向异性在磁鞘中被显著放大；

The solar wind , carrying the plasma and IMF , is slowed down by the magnetosphere , produce the bow shock region and the magnetosheath .

携带着行星际磁场的太阳风被地球磁层所减速产生了弓激波以及磁鞘区。

For the certain discontinuities with specific initial configuration , the magnetosheath magnetic reconnection , as an important consequence of such evolution , has been confirmed by simulation and observation .

对于某些具有特定结构的间断面，磁鞘磁场重联是这一演化过程的必然结果，并且已经被计算机数值模拟和空间卫星观测所证实。

The magnetic holes in the planetary magnetosheath are commonly believed generated by mirror instability , while there are many different kinds of mechanisms about magnetic holes in the interplanetary space .

对于在行星磁鞘中观测到的磁洞，一般认为是由镜像不稳定性产生的。而对于在太阳风中观测到的磁洞的产生机制目前还存在着争议。

Unlike the magnetopause reconnection , the magnetosheath reconnection can only lead to the topology change of IMF and the acceleration and heating of the magnetosheath plasma .

不同于磁层顶的磁场重联，磁鞘重联仅仅会导致行星际磁场的结构位形发生变化以及磁鞘区的等离子加热以及加速。

The distributions of the magnetic field fluctuation characteristics near the ecliptic plane in the magnetosheath are discussed by using the MHD model for describing variations of the interplanetary magnetic field fluctuations across a shock wave .

本文利用行星际起伏通过激波后的变化的MHD模型，具体讨论了地球磁鞘中磁场起伏特性在黄道面内的分布。

An enhancement of magnetospheric energetic particle flux was observed inside the magnetosheath portion of the flux tubes . This implies that the flux tubes connect the magnetosheath with the magnetosphere through the magnetopause .

在通量管的磁鞘部分观测到磁层能量粒子流量的增强，这表明通量管通过磁层顶将磁鞘和磁层内部连通起来了。

Magnetic hole was first observed in the interplanetary space , and after that , there were many observations of magnetic holes in planetary magnetosheath , in the vicinity of comet cone and Io , and even in the terrestrial cusp .

磁洞首先是在太阳风中被观测到的，后来在行星磁鞘、彗尾、木卫一附近以及地球磁层极尖区都有关于磁洞的报道。

The approximate analysis solution shows that our theoretical results can explain better the statistic results obtained by Belcher and Davis ( 1971 ) and Whang ( 1973 ) who analysed observation data from Mariner 5 and Explorer 34 in the interplanetary space and the magnetosheath .

得到的近似解析解表明：由本模型所得到的结果能较好地解释人们对行星际、磁鞘层观测资料进行统计研究所得到的认识。
