为减小涡流损耗，提高工作效率，文献［8］提出了一种既经济又有效的对Terfenol棒进行切割的新方法。本文给出了一种简便的计算方法，用以计算满足极限工作频率要求的切割份数，并附以算例，与实际相符合。
In order to reduce the eddy current loss and improve the working efficiency, a new method for cutting Terfenol rods is proposed [8]. It is an economical and effective method. In this paper, a simple calculation method is given to calculate the number of cutting parts that meet the requirements of the limit working frequency. The examples are attached with the actual ones.
