简要分析了引起K-489电动机副极线包松动的原因，并采取相应针对性的措施加以处理，效果较好。
This paper simply analyzes the causes of looseness default of inter pole coils of electrical motor K-489, and bring forward relevant measures to treat this default, which achieves fairly good effect.
在可怜的妮蒂被冠上了电影史上最糟糕的名字之一，以及一副大得吓人的眼镜，但是跟许多困于无法表达爱情的极客女孩不同，她不需要通过变身来赢得一个男友。
Poor Needy is saddled with one of the worst names in movie history and some seriously oversized owl specs, but unlike many date-challenged girl geeks, she doesn't need a makeover to get a boyfriend.
它具有辅助电路简单，辅助电路的电感、电容和二极管的电流电压应力小，副边占空比损失小等优点。
This auxiliary network has the advantages such as its circuit is simple, the current stresses and voltage stresses on its components are small.
此外，这种结构包括在副集电极之上的有源区(集电极)、在有源区之上的基极和在基极之上的发射极。
In addition, this structure includes an active area (collector) above the sub-collector, a base above the active area, and an emitter above the base.
当电机作四极运转时，先按二极运转启动，然后切换开关使主绕组抽头A2与A4连接电机既作四极运转，此时副绕组开路。
When the motor runs in four-pole mode, it is started at two-pole mode and taps A2 and A4 are then connected together. In the meantime secondary winding is open.
