摘  要:为优化重力仪器选择,提升台站地震监测能力,收集整理姑咱台DZW重力仪和燕子沟台gPhone重力仪2021—2023年观测资料,对比分析两套重力仪的记录情况、观测精度、稳定性和同震响应形态,结果显示两套仪器都能清晰完整记录到固体潮汐重力波,gPhone重力仪在观测精度、稳定性与同震响应方面的性能略优于DZW重力仪。燕子沟台为无人值守台站,运维距离较远影响了gPhone重力仪的运行情况;姑咱台市电停电、仪器老化是影响监测质量的主要因素。To optimize the selection of gravity instruments and enhance the seismic monitoring capability of the station,this article collects and organizes the observation data of the Guzan DZW gravity meter and the Yanzigou gPhone gravity meter from 2021 to 2023.We compared and analyzed the recording situation,observation accuracy,stability,and coseismic response of the two sets of gravity meters.The results show that both sets of instruments could record solid tidal gravity waves clearly and completely.Moreover,the gPhone gravity meter shows a slightly better performance in observation accuracy,stability,and coseismic response than that of the DZW gravity meter.The Yanzigou station is an unmanned station.The long distance for operation and maintenance has affected the operation of the gPhone gravity instrument.Moreover,power outage and instrument aging at Guzan Station are factors that affect the quality of monitoring.
