摘要
基于水平摆和垂直摆两种摆式倾斜仪不同的工作原理,对比分析库尔勒台的这两种倾斜仪的观测精度、年变幅、年零漂、稳定性、映震能力,研究观测环境和天气过程等不同影响因素对观测造成的干扰差异性,综合评价水平摆和垂直摆仪器的各项参数和优劣性,同时提取了可识别的前兆异常特征,为数据处理、资料分析、震情跟踪提供科学的依据。
Based on the different working principles of horizontal pendulum tiltmeter and vertical pendulum tiltmeter,the observation accuracy,annual variation,annual zero drift,stability and earthquake reflecting ability of the two tiltmeters at Korla Station are compared and analyzed.The interference differences caused by different factors such as observation environment and weather process are studied,and the horizontal pendulum is comprehensively evaluated.At the same time,the identifiable characteristics of precursory anomalies are extracted to provide scientific basis for data processing,data analysis and earthquake tracking.
