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,行星際磁場(chǎng)的螺旋結(jié)構(gòu)是產(chǎn)生日球赤道面內(nèi)雙重激波對(duì)結(jié)構(gòu)東西不對(duì)稱性的主要原因。
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 ) 這種行星際磁場(chǎng)( imf )的磁力線基本上都是往外拉的,也就是徑向的(即不是指向,就是背向太陽(yáng)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飛船在亞暴期間觀測(cè)到的場(chǎng)向電流的特性,包括場(chǎng)向電流所伴隨的行星際磁場(chǎng)地方時(shí)與
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 于一九九七年由美國(guó)發(fā)射,它能分析從太陽(yáng)釋放出來(lái)帶電荷粒子的物質(zhì)組合及行星間的磁場(chǎng),為我們提供太陽(yáng)活動(dòng)事件中釋出物質(zhì)的重要資料。
