摘要
超磁致伸缩材料(GMM)是一种新型的功能材料,其磁致伸缩系数与磁场强度、温度、压力等有关。以超磁致伸缩高速响应电磁阀的研究为背景,介绍超磁致伸缩材料特性参数的测量方法,及适用于超磁致伸缩材料特性参数测量的测试装置。
The Giant Magnetostrictive Material （GMM） is cient is relavent to magnetic density, temperature, pressure, a new function material, its magnetostrictive coeffietc. The study of giant magnetostrictive high-speed magnetic is used as background, introduced the manner of measuring the magnetostrictive coefficient, and the experiment system.
