【摘要】 山西临汾中心地震台SSQ-2Ⅰ石英水平摆和VS型垂直摆倾斜仪同属数字化倾斜类前兆仪器,两摆式倾斜仪虽结构不同,但观测物理量一致。文章对同场地观测的两摆式倾斜仪记录资料从数据完整率、年变幅、年零漂、相对噪声水平、相关性、映震能力等多角度进行对比分析,以求对两仪器的运行效能进行综合评价。更多还原

【Abstract】 Both SSQ-2 Ⅰ quartz horizontal pendulum and VS vertical pendulum tilt meters in Linfen Central Seismological Station of Shanxi are digital instruments for tilt observation,with same principles and physical measurement,but different structures.In order to comprehensively evaluate operational performance of the two kind of instruments,multiple perspective analysis and comparison,from aspects of data integrity rate,annual variation amplitude and zero drift,relative noise level,Venedikov harmonic analysis,correlation analysis and earthquake reflecting ability,for two kinds of pendulum tilt meters placed at same observation site in Linfen Central Seismological Station are taken.更多还原
