各种用途的换能器,都是利用它把电能转化为机械能。美国艾姆斯实验室开发了一种新型换能材料——三联苯—D。这种材料能通过磁场作用产生机械运动,比通常用的压电陶瓷和电致伸缩材料更为优越,可用在诸如声波定位装置、微定位装置、液压系统、阀门和燃料充注系统以及自动化技术等方 Transducers of various uses are used to convert electrical energy into mechanical energy. Ames laboratory in the United States has developed a new type of transduction material - terphenyl-D. This material produces mechanical motion through magnetic fields and is superior to commonly used piezoelectric ceramics and electrostrictive materials in applications such as sonic positioning devices, micropositioning devices, hydraulic systems, valves and fuel filling systems, and automation technology Other parties
