QHXC-75型分量核子旋进磁力仪是我厂在长春地质学院、安徽省地震局的协助下,自行设计研制的地磁观测仪器。它主要用于地震的预测预报、物理探矿、地磁研究等方面。仪器不但能适用于地震台、站对地磁变化作长期连续观测,亦可用于流动磁测;不但能测量地球磁场总向量(?)的绝对值,同时还可以测量地球磁场的水平分量(?)和垂直分量(?)的绝对值。 QHXC-75-type component nuclear precession magnetometer is my factory in Changchun Geological College, Anhui Province Seismological Bureau with the assistance of their own design and development of geomagnetic observation instruments. It is mainly used for earthquake prediction, physical prospecting, geomagnetic research and so on. The instrument not only can be applied to the seismic station, the station can make long-term continuous observation of the geomagnetic change, but also can be used for mobile magnetometry; not only can measure the absolute value of the earth’s magnetic field total vector (?), But also can measure the horizontal component of the earth’s magnetic field And the absolute value of the vertical component (?).
