GM4磁通门磁力仪的供电设备对观测数据的影响

摘要

通过对我国GM4磁通门磁力仪使用的各种电源设备所产出的观测数据动态曲线的对比研究,认为电源设备对观测数据的影响不容忽视,市电结合UPS方式是最为合适的供电选择。%It＇ s very important to choose the power for GM4 fluxgate magnetometer. The power equipments of GM4 fluxgate magnetometers at present and their influences are compared and analyzed in the paper, and the results show that the UPS as the power supply of GM4 is an appropriate choice.
