研究人员说，一种叫做磁滞的过程会引起热能损失，但这种新合金具有低磁滞特性。

A process called hysteresis causes some of the heat energy to be lost, but this new alloy has a low hysteresis, the researchers say.

一般说来，这些材料不显示磁滞现象。

As a rule these materials do not show hysteresis.

The electromagnetic-hysteresis yarn tensioning device was discussed in this article.

得出磁滞损耗功率与频率、磁通密度及温度的经验公式。

An empirical formula describing the dependence of the power of hysteresis loss on frequency, magnetic flux density and temperature was derived.

低磁芯损耗，饱和磁通密度较高。
