行星际磁场 meaning in Chinese
interplanetary magnetic field, imf
Examples
- 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。 - 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） 。 - 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 - 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。 - Value , and the current density and intensity versus the substorm phases . moreover , the characteristics of substorm current wedge are given special attention . it is found that the density and intensity of facs reach their peak during the expansion phase , the onset of the expansion phase is triggered when imf is changed to southward from northward or the southward imf decreases , and the positions of onset are most likely to be at the edge of plasma sheet near the earth
值分布以及场向电流强度和密度随亚暴位相的变化，并着重分析了亚暴电流楔的特征。结果表明，亚暴膨胀相的场向电流强度和密度都达到极大值亚暴的膨胀相是由行星际磁场转向或南向分量变小触发的，其起始位置很可能位于近地等离子体片内边缘。
