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。

The step through test and independent activity were used to observe effect of uneven constant magnetic field pole N and S on learning and memory impairment induced by hypobaric hypoxia .

用避暗实验法和自主活动法，分别观察了非均匀恒磁场N极、S极对急性低压缺氧引起的学习记忆障碍的影响。
