摘　　要：为了对四川攀枝花南山地震台升级改造后的DSQ水管倾斜仪的稳定性和观测资料的可靠性进行评估,选取改造后的DSQ水管倾斜仪2022—2023年的观测资料,利用Venedikov调和分析、数据对比分析、同震响应分析等对地球固体潮记录情况、数据连续率和完整率、年零漂和年变幅、观测资料内在精度以及干扰因素等进行评估分析。结果显示:仪器记录资料的连续性和完整性较高;仪器工作状态稳定,能清晰地记录到地球固体潮汐变化,记录数据符合形变学科要求规范;影响仪器精度的主要因素为观测环境干扰。To evaluate the stability and reliability of the observation data,we selected the upgraded DSQ observation data from 2022 and 2023,using multiple methods such as Venedikov harmonic analysis,comparative data analysis,seismic response analysis of the earth solid tides,data continuity and completeness rates,zero drift and annual amplitude monitoring,internal data accuracy and interference factors.The results show that the continuity and completeness of the instrument record data are solid.The instrument can stably and clearly record the tidal changes of the earth solid,which meets the requirement for deformation discipline.The main factor affecting the instrument accuracy is the interference from observation environment.
