摘要
运用频谱分析、互相关分析及观测精度等方法,对朝阳地震台石英水平摆倾斜仪与VP宽频带倾斜仪2014年1月至8月的数据进行分析。通过分析得出,VP记录的频率成份较石英水平摆多且复杂,其记录的信息要多于后者,VP垂直摆观测精度总体上优于模拟观测,可以替代石英水平摆。
We analyze data produced by VP Broadband clinometer and SQ Quartz horizontal pendulum clinometer in ChaoYang station from January to August,using Spectral analysis method, correlation analysis and Observation accuracy,and knew that frequency component recorded by VP is much more than Quartz horizontal pendulum clinometer and more complexity.This result show that the information recorded by VP is more than Quartz horizontal pendulum clinometer.VP Vertical pendulum is better than analogue observational Optical recording data,and may replace Quartz horizontal pendulum.
