Note:For CM1-160,225 four-poles breakers, the instantaneous release of N-pole (short-circuit protection) have no 5 In spec.

注：对CM1-160 、225四极断路器，其中性极（N ）的 瞬时 脱扣器（ 短路保护）均 无5In规格。

In fact, however, the N-pole side and the S-pole side are excited through the same field winding, which means that this model shows MMF that is only half the actual value.

事实上，N极边和s极边由相同的励磁绕组励磁，这意味着模型中的磁动势只是实际磁动势的一半。

ZetaTalk Explanation9/30/2009: Any plot of a magnetosphere will show output from the N Pole, regardless of what activity might be ongoing at the S Pole.

齐塔人之声2009.9.30解释：任何对磁气圈的描绘都将显示从北极的输出，无论南极在进行什么样的活动。
