The reluctance seismogroph implies a variation of the principle of the moving-coil seismograph. 磁阻地震仪改变了动圈地震仪的工作原理。
Compared with the situation abroad, the domestic application of weak magnetic field measurement instruments based on the thin-film magnetoresistive sensors is limited. 与国外相比,国内基于薄膜磁阻传感器的微弱磁场测量技术的应用还很有限。
