hard axis meaning in English

难磁化轴

A better low - field magnetostrictive sensitivity has been obtained when the ecmm is magnetized along the hard axis of the magnetostrictive layer
沿磁致伸缩层难轴方向磁化时,多层膜的低场磁致伸缩灵敏度较好。
If the magnetic anisotropy of the magnetostrictive layer is much larger than that of the soft layer , the magnetic hysteresis and magnetostriction of the ecmm magnetized along the easy axis of the magnetostrictive layer are different from those of hard axis of the magnetostrictive layer
当磁致伸缩层磁各向异性与软磁层磁各向异性相差较大时,沿磁致伸缩层的易轴方向或难轴方向磁化,多层膜的磁学及力学性质差别较大。
