磁极

Quantum transition which causes the changes of the magnetopolaron lifetime is occurred in the quantum system due to the electron-phonon interaction and the influence of external temperature which is the magnetopolaron leap from the ground state to the first-excited state after absorbing a LO-phonon.

由于电子-声子相互作用和外界温度的影响导致了量子体系的跃迁，即磁极化子吸收了声子的能量由基态跃迁到激发态，造成极化子在基态的寿命发生变化。

The development and application of the conventional coreless generator and electromagnetic damper are introduced at the beginning of this paper.

文中简要介绍了常规空心杯电机与电磁阻尼器的结构、发展和应用，基于Ansoft公司的电磁场分析软件Maxwell 2D学生版软件建立了电磁阻尼器静磁场的二维仿真模型，分别对不同充磁方向、极弧系数、磁极对数的气隙磁密分布进行了静态仿真分析，得出了相应结论。

The globe will bElike an office or home.

也就是说作者在本文中主要讲述磁极变化这一奇妙的自然现象。

According to Biot-Savart law, the magnetic induction at the diameter position of the spin axis is calculated. Furthermore, using the internal and external radius of the Earth's outer core as well as the radius of the Earth and the magnetic induction at the Earth's magnetic pole, the volume charge density and surface charge density of the Earth's outer core have been obtained.

先根据毕奥-萨伐尔定律计算球形模型绕自转轴旋转时在自转轴直径上产生的磁感应强度；再利用已知的地球外核的内外半径及地球半径和磁极处的磁感应强度值，计算出地球外核的电荷体密度及面密度。

The centimeter-gram-second electromagnetic unit of magnetic intensity, equal to the magnetic intensity one centimeter from a unit magnetic pole .

奥斯忒厘米、克、秒制中磁场强度单位，等于离单位磁极一厘米处的磁场强度

Magnetic poles leaded from this kind of magnetic anisotropy may be favor of oallback of magnetic material worn by chiton to supply the needing of iron of new tooth, and they may also be favor of obtaining food by chiton better.

这种磁各向异性产生的磁极有利于石鳖将磨损的磁性矿物质"回收"，补充新生牙对铁元素的需求，并且还有可能有利于石鳖更好的获取食物。

They are almost certainly out there: monopoles plays a pivotal role in the widely accepted"grand unified theories", for example.

这些单磁极几乎必然地在什么地方存在着：单磁极在&大统一理论&中起着关键性的作用。

The scientist has thought of two solutions: One kind is the gas floats the law, even if the train massive jet uses its reaction to the railway rail ground to do the best you can the train to float off; Another kind is magnetism floats the law, namely uses between two magnetic poles of the same name between the magnetic repulsions or two different famous magnetic poles the magnetic attraction causes the train to surface the boat from the railway rail.

科学家想到了两种解决方法：一种是气浮法，即使火车向铁轨地面大量喷气而利用其反作用力把火车浮起；另一种是磁浮法，即利用两个同名磁极之间的磁斥力或两个异名磁极之间磁吸力使火车从铁轨上浮起来。
