| 摘 要： | 讨论了利用两根磁致伸缩棒（Ｔｂ＿０，＿３Ｄｙ＿０，＿７Ｆｅ＿（１，９５））组成的力矩激励器的特性．简单的理论和实验表明：力矩激励器的特性对力矩导纳测量结果基本上不会造成影响，但显然会影响力矩激励器激发转动的效率．最后计算了这个效率．

| Abstract: | In this paper the performances of the moment exciter which is composed oftwo magnetostrictive rods(Tb_0._3Dy_0._7Fe_(1,95))have been discussed.Both simpletheory and experiments indicate that the performances of the moment exciter donot basically influence the measurement results of the moment mobilities, but doaffect the efficiency for exciting the rotation. The efficiency for exciting the rotationhas also been calculated in this paper. |
