摘要
自制了两台磁致伸缩仪.一台是借助于磁化强度小角度旋转原理制成的“薄窄非晶合金条带磁致伸缩仪”;另一台是用Fabry-Perot 干涉原理制成的“高温磁致伸缩仪”.介绍了仪器的原理,结构及性能.
This paper presents two magnetostrtion apparatuses we have made.One isused to measure narrow-thinamorphous ribbon by means of small-angle-magn-etization-rotation.The other is a“High Temperature Magnetostriction Apparatus”which works on the theory of Fabry-perot interferometer.The paper alsointroduces the structure,themeasurement fundamentals and characteristics ofthe apparatuses.
