摘要
从干扰因素、连续性、稳定性、观测精度和映震能力等方面对徐州地震台SQ-70模拟石英水平摆倾斜仪和VP型宽频带垂直摆倾斜仪2014-01~12数据进行对比分析后认为,后者性能明显优于前者,并能实现远距离数据快速传输,有利于及时捕捉地震的短临信息和资料共享。
In October 2013 Xuzhou seismic station installed the VP broadband vertical pendulum tiltmeter（VP）,instead of the original SQ-70 type analog quartz horizontal pendulum tiltmeter（SQ-70）,for the sake of tilt tide deformation technological upgrade.In order to comprehensively evaluate the operational performance of the two kinds of instruments placed at the same observation site in 2014,multiple perspective analysis and comparison,from the aspects of interference factors,continuity,stability,observation precision and earthquake reflecting ability are comparatively analyzed.VP is superior to SQ-70,and can reach precision of minute value and transmit date rapidly for long distance,show real-time anomalies accurately,and share data.
