| 1. | A preliminary analysis shows that the east - west asymmetry in the heliospheric equatorial plane is mainly attributed to the spiral structure of the interplanetary magnetic field
初步分析表明，行星际磁场的螺旋结构是产生日球赤道面内双重激波对结构东西不对称性的主要原因。 |
| 2. | As the wind carries this interplanetary magnetic field ( imf ) away from the sun , the field lines typically stretch out so that they are directed radially ( pointing toward or away from the sun )
这种行星际磁场（ imf ）的磁力线基本上都是往外拉的，也就是径向的（即不是指向，就是背向太阳的方向） 。 |
| 3. | The characteristics of the field - aligned currents facs measured by isee 1 and 2 satellites during substorms are studied . these characteristics include the variations of facs with the interplanetary magnetic field , local time ,
分析了由isee - 1和isee - 2飞船在亚暴期间观测到的场向电流的特性，包括场向电流所伴随的行星际磁场地方时与 |
| 4. | Was launched in 1997 by the united states . it is capable of measuring the composition of charged particle from the sun and the interplanetary magnetic field . it gives us important information on the materials released during solar events
于一九九七年由美国发射，它能分析从太阳释放出来带电荷粒子的物质组合及行星间的磁场，为我们提供太阳活动事件中释出物质的重要资料。 |
| 5. | Was launched in 1997 by the united states . it is capable of measuring the composition of charged particle from the sun and the interplanetary magnetic field . it gives us important information on the materials released during solar events
于一九九七年由美国发射，它能分析从太阳释放出来带电荷粒子的物质组合及行星间的磁场，为我们提供太阳活动事件中释出物质的重要资料。 |
| 6. | The background interplanetary magnetic field is spiral with a vanishing south - north component , the initial ionosphere is dominated by the region field - aligned current ( fac ) and the corresponding dawn - dusk electric field , and the interplanetary shock collides with the earth along the sun - earth line
背景行星际磁场为螺旋场，南北分量为零；初始电离层由区场向电流和相应的晨昏电场所主导；行星际激波沿日地连线方向撞击地球。 |
