Hence, there is a significant discrepancy with measured results (to be discussed below) in the area of negative field current.

因此，与反向励磁电流区间的测量值(下面讨论)存在一个显著差异。

With zero field current, armature back yoke flux density is 1.2 t.

励磁电流为零时，导磁机壳的磁密为1.2 T。

Test results show that the regulator operates well in the regulation of field current and the reversal of field current...

试验结果表明该调节器可以很好的调节励磁电流，并能可靠地实现励磁电流的反向。

That is we make animation file when you put the current to the coil of the field, getting established magnetic field.

即通过制作动画效果,当你将电流,输送到线圈上，形成磁场。

We can actually see spatially all the details in the field animated as you turn the current on and off.

我们能看到,所有细节的空间动画分布,就在你打开电流和切断的时候。
