In other embodiments, pole piece elements are added to focus the magnetic field on two of the four regions.

在其它的实施例中，增加了磁极片元件，以便将磁场聚焦到4个区域中的二个上。

Was founded in 1999, its predecessor, Universal Mold Factory Cixi are experienced 8 years of arduous pioneering, in 2007, renamed as Cixi Ci Yu Motor Parts Factory, the company in the united struggle of all the employees, in the vast numbers of customers still do not transfer the trust and support, Tsz Yuk motor has been rapid and steady development, has successfully developed a red double-rotor slot mode, blanking duplex mode, the entire complex mode rotor, pole piece double dies, compound dies chip Yoke , fan-shaped tablet die complex, high-speed machine Notching Notching told alloy molds for dozens of special silicon steel motor dies, electrical silicon steel varieties covering most of the production tooling required type, in the years of production practice, accumulated a wealth of production experience, forming a complete set of processing technology.

慈钰电机公司创建于1999年，其前身是慈溪环球模具厂，经历8年的艰苦创业，于2007年更名为慈溪慈钰电机配件厂，公司在全体员工的齐心拼搏下，在广大客户始终不移的信任和支持下，慈钰电机得到了迅速而稳定的发展，先后成功开发了定转子复式冲槽模，复式落料模，定转子全复模，磁极片复式冲模，磁轭片复式冲模，扇形片复冲模，高速冲槽机专用合金告诉冲槽模等几十种电机硅钢片专用冲模，品种覆盖电机硅钢片生产需要的大部分模具种类，在多年的生产实践中，积累了丰富的生产经验，形成了一套完整的加工工艺。

Aurora Ovals are elliptical zones which produced by Aurora, the centered by polars magnetic in Arctic and Antarctica.

极光卵是极光粒子沉降以磁极为中心在地球南北极地区形成的椭圆带状区域。

At low temperature, both the positive and negative magnetoresistance effect can be observed for all the samples. The s-d exchange interaction induced spin-splitting, the formation of bound magnetic polarons, and the magnetic field suppressed spin-disorder scattering were competed for the MR behavior.

另外，在低温时所有样品都表现出较大的正磁电阻，我们认为正磁电阻效应是由于s-d电子交换相互作用引起的自旋劈裂造成的，而高场时出现的负磁电阻效应则可能归因于磁场导致的束缚磁极化子的破损和自旋散射的抑制。

Numerical results indicate that the mean number of phonons for strong-coupling magnetopolaron will decrease with increasing temperature.

数值结果表明，非对称量子点中强耦合磁极化子的声子平均数随温度的升高而减小。

Especially, increases when there is the magnetic fild, because of the interactions was strengthened between the electrons and phonons.

另外，由于稳恒磁场的存在，使磁极化子的自陷能增大，这主要是由于稳恒磁场的存在，使电子—声子间的相互作用增强，极化子效应增大而引起的。

An auxiliary power motor with improved structure includes wheel shell, rotor ring, stator plate, central wheel axle and control circuit.

一种改良结构的辅助动力马达，包括轮壳、转子环、定子盘、中心轮轴及一控制电路，转子环的内环面埋设磁铁，定子盘周围固设环形矽钢片，其外环面具有多个T形齿牙，其齿数为非转子环磁铁数的公倍数，矽钢片设有三相星形线圈绕组，且于定子盘电机最佳启动角度处设有霍耳元件组；借此将定子盘固设于中心轮轴，令轮壳夹设住转子环并套设于中心轮轴两侧，当转子环旋转时，即可降低磁极间的钝齿转矩，令电动车行进更加顺畅无噪音。

Temperature dependence of the the vibration frequency and the mean number of phonons for weak-coupling magnetopolaron in an asymmetric quantum dot were studied by using Huybrechts linear combination operator and Lee-Low-Pines variation method.

采用Huybrechts线性组合算符法和Lee-Low-Pines幺正变换法，研究了非对称抛物量子点内弱耦合磁极化子的振动频率和声子平均数的温度依赖性。

Performance of the motor which has fractional slot winding is compared with the original motor's.

最后，本文还对电机的转子磁钢进行了磁极优化从而降低转矩波动。
