电磁铁线圈

Before the thermal field is calculated, stable temperature rises in each part of the electromagnet are unknown, so it is impossible to determine the power and convectional heat transfer coefficients at the stable temperature rise.

在进行温度场的计算之前，电磁铁各部件的稳态温升是未知量，故线圈达到稳态温升时的发热功率及对流散热系数不能确定。

Back in the Gold age of sound reproduction, an electromagnet was the only means of providing a magnetic field to the voice coil of an electrodynamic loudspeaker driver for sound reproduction, until the permanent magnet made it's appearance, it was a great idea back then to replace those bulky and expensive power supplies to feed the electromagnet coils, but something very subtle happened to the sound quality!

早在黄金年龄的声音复制，电磁铁是唯一的手段，提供了一个磁场对音圈的电动扬声器声音驱动程序的复制，直到永久磁体它的外观，它是一个伟大的想法，以取代当时那些笨重而昂贵的电源供应系统，饲料的电磁铁线圈，而是发生在非常微妙的音质！

The coil acts as an electromagnet, and around it is strong permanent magnet.

线圈充当着电磁铁，围绕着它的是强力的永久磁铁。

In the AMB system, a power amplifier which provides magnetic coil with exciting current to produce electromagnetic force, is one of the main components.

由于实验的需要，研究人员常用的磁场发生装置有：永磁铁、电磁铁、亥姆霍兹线圈和螺线管。

Permanent magnet can provide for a maximum intensity of the magnetic field around Tesla, Helmholtz coils and solenoids can provide alternating magnetic field or relatively uniform magnetic field, and solenoids can also be used to provide strength for the solenoid around 10 Tesla.

其中永磁铁能够提供强度最大为1特斯拉左右的静磁场，亥姆霍兹线圈和螺线管可提供交变磁场或相对均匀的磁场，也可用螺线管提供强度为10特斯拉左右的超强静磁场，电磁铁则可产生强度为几百毫特斯拉或特斯拉级的静磁场。

In the electronic system, a power amplifier which provides magnetic coil with exciting current to produce electromagnetic force is one of the main components. General commercialization of power amplifiers can not meet the application requirements, but should be designed.Power amplifiers are divided into linear amplifier and switching amplifier.

磁悬浮轴承是典型的机电一体化系统，在其电控系统(传感器、控制器和功率放大器)中，功率放大器具有重要的作用，它向电磁铁线圈提供相应的控制电流以产生所需要的电磁力。

Frame type solenoid features simple structure, large power, magnetizer framework, open winding and long stroke.

推拉式电磁铁是具有结构简单，功率大，以导磁体作框架，畅开式线圈的优点，同时独具行程长的特点。

During the process of calculating the stable temperature rise of an electromagnet, the power in the cold state can be used as a heat source if electrical resistance changes of the coil from the cold state to the stable state have few effects on the power.

在计算电磁铁的稳态温升时，若线圈电阻从冷态到稳定发热时的变化对发热功率影响不大，可将冷态时的发热功率当作热源进行计算，应用稳态热路法计算线圈的稳态温升。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
