| 摘 要： | 目前在我国的物理探矿工作中,比较多地使用了高精度的轻便型石英弹簧重力仪进行重力测量。在野外的实际工作中仪器的稳定性是一个问题,看来这一问题与仪器的零点掉格很有关系。仪器的这种不稳定性影响了观测精度的提高。作者拟从研制这种重力仪的工作经验出发来讨论这个问题。

| Abstract: | This is a preliminary report on some experimental work done by the author relating to the drifting of the zero of a quartz spring gravimeter. Drifting caused by different factors was analysed and separated from each other in order to examine their respective characteristics. Treatments by etching the quartz system by hydrofluoric acid solution and by supersonic vibration did not improve the drifting rate of the gravimeter. |
