本文用二维磁测量技术测量了在交变和旋转磁场下的任意动态磁致伸缩，三轴应变片的输出方向分别与试样的轧制方向倾斜45/spl °/ 90/spl °/和135/spl °/。通过这种技术，任意动态磁致伸缩由应变张量表示。也就是说，张量的元素可以与每个方向上测量的磁致伸缩进行比较。因此，在交变和旋转场激励下，任意方向的磁致伸缩可以由张量表达式得到。
Arbitrary dynamic magnetostriction under alternating and rotating field is measured by using a two-dimensional magnetic measurement technique with a three-axial strain gage, which provides its output in a direction inclined 45/spl deg/ 90/spl deg/, and 135/spl deg/ to the rolling direction of a sample sheet. By this technique the arbitrary dynamic magnetostriction is expressed by a strain tensor. That is, the elements of the tensor can be compared with the measured magnetostriction in each direction. Therefore, the magnetostriction in an arbitrary direction under alternating and rotating field excitation can be obtained from the tensor expression.
