磁滞

Therefore except for the hysteretic losses, it is necessary to consider the eddy current loss and coupling loss in application of HTS tapes at temperature regions near 4. 2K and 30K.

因此，在4.2K和30K温区高温超导带材的应用中除了磁滞损耗外，必须考虑涡流损耗和耦合损耗的影响。

This is the sum of the hysteresis loss factor, eddy current loss factor and residual loss factor.

式中 tan 〥 h 为磁滞损耗因数， tan 〥 e 为涡流损耗因数， tan 〥 r 为剩余损耗因数

The empirical formula can also be used to evaluate hysteresis loss as well as the temperature distribution of the yoke ring.

In the experimental research, the levitation force of a HTS above a permanent magnetic guideway was first investigated in the case of zero-field cooling. The hysteresis of the levitation force curve and the interaction between a HTS and the applied magnetic field were explained by the Bean model, and the effect of the measuring precess on the levitation force was further analyzed.

实验研究中，首先研究了零场冷条件下高温超导体在永磁导轨上方的悬浮力特性，借助于Bean模型分析了悬浮力曲线的磁滞特性，阐述了高温超导体与外磁场间的相互作用原理，在此基础上进一步分析了悬浮力测试过程对悬浮力测试结果的影响。

In 1956, Meiklejohn and Bean observed that field cooled, partially oxidized, Co particles exhibited hysteresis loops displaced along the magnetic field axis.They attributed this phenomenon to the exchange interaction at the interface between the ferromagnetic Co core and the antiferromagnetic CoO shell.

Meiklejohnc 和 Bean 在 1956 年从成长良好的单晶钴与其表面氧化层的微小颗粒，在强磁场下冷却，观察到磁滞曲线不以磁场零点对称，他们将此现象归因於在内部的 Co核与外部的 CoO 壳之界面产生交互影响。

From two sets of field test data, i.e., the instantaneous voltage versus current curves under different loading conditions, the hysteresis loops can be approximated to any desired degree of accuracy through a supervised training session.

从二种不同额定下所得的电压、电流瞬时值，透过监督式学习的过程，可以获得精确的变压器磁滞回路模型。

To enhance the precision of servo systems, friction should be adaptively compensated. With considering the hysteresis in piezo-based micro-feeding components, it is proposed to compensate friction and hysteresis simultaneously in this paper.

根据运动控制发展的需要，本文提出将机械伺服系统中出现的摩擦现象与磁滞现象综合考虑的理念。

This means that above 700°C there can be no heating of the material due to hysteresis losses.

这意味着，上述700℃就没有物质由亿磁滞损耗加热。

The simulation results also indicate that the neural network predictive can effectively solve the problem induced by hysteresis.

However, Steinmetz was the first one to focus on hysteresis motor and created a good basis for B.

史坦密斯是第一个专注於磁滞马达研究的人，他造就了一个良好的基础，而这个基础使得擅长理论却非为工程师的B。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.
