有磁性流动指示器。将该装置引入，移动电子，流动开始。这种流动引导自由电子进入装置。
There are magnetic flow directors. When you engage the device, you shift the electrons and a flow is initiated. This flow inducts free electrons into the device.
这些小磁铁可以自由转动，平时它们的方向杂乱无章，磁性相互抵消，整个物体不显磁性。
These small magnets can free rotation, peacetime its direction desultorily, magnetic mutual offset, the whole object does not show magnetism.
结果表明，不同构象下各体系有效交换积分值都小于零，自由基间表现为反铁磁性耦合。
The results show that the effective exchange integral values are less than zero under different conformations, so the radicals display the anti-ferromagnetic coupling.
