| 1. | It is what is called a dipole field with a north and south pole 它就是所谓的偶极场? ?具有一个北极和一个南极。 |
| 2. | A . c . magnetic dipole field 交流磁偶极子场 |
| 3. | A . c . electric dipole field 交流电偶极场 |
| 4. | One of these patches has normally directed flux ( in the same direction as the overall dipole field in that hemisphere ) ; the other has the opposite , or reversed , flux 斑块之一具有正常方向的磁通量(与该半球整体的偶极方向相同) ;另一个斑块的通量方向则是相反的。 |
| 5. | Hulot ' s team argues that the growth of these reversed patches , presumably eddies that are working against the primary motion of the core , can explain the current decline in the dipole field 余洛的研究小组认为,假如此区块是一种与主要地核运动相抗衡的漩涡区,那麽此区块的增长便可以解释现今磁偶极场的衰减现象了。 |
| 6. | One three - dimensional simulation ? which had to run for 12 hours a day every day for more than a year to simulate 300 , 000 years ? depicted the onset of a reversal as a decrease in the intensity of the dipole field 一个三维的模拟(必须每天运算12小时,并且持续一年,才能得出30万年的模拟结果)所描绘出的反转事件,是开始于偶极场强度的衰减。 |
