摘要
为配合中国地震局“首都圈防震减灾示范区系统工程项目”项目的实施,笔者研制了JDF-1型力平衡式反馈拾震器井下地震计,介绍了仪器的主要技术指标、结构特点及在地震观测、工程振动测量中的应用。
Model JDF-1 Borehole Seismometer is a force balance feedback seismometer.Besides describing the main technical specifications and the structural characteristics of this seismometer,this paper recounts the application of this instrument to the seismic observation and the engineering vibration measurement.
