在我国,野外重力测量主要是使用石英弹簧重力仪,这种仪器的灵敏系统是由纯石英制成的,所以人们通常认为这种仪器不受地磁场的影响。一切规范、守则也都没有注意到要防范地磁场对石英弹簧重力仪的影响。但是1978年K·Civi等的试验证明上述认识是不全面 In our country, the gravity measurement in the field mainly uses the quartz spring gravity meter. The sensitive system of this instrument is made of pure quartz, so people usually think that this instrument is not affected by the geomagnetic field. All norms, the code also failed to pay attention to prevent the magnetic field on the quartz spring gravimeter. However, tests such as K · Civi in ​​1978 proved that this understanding is not comprehensive
