| 摘 要： | 怀来地震台伸缩仪观测中存在一种干扰,此干扰起止时间、持续时间、干扰变化幅度每年基本相当.本文就引起此干扰的因素、干扰机理展开讨论与分析,并提出一种消除此干扰的方法,剔除怀来地震台伸缩仪数字化观测资料中的干扰后,发现与地震的对应关系较好,提高了地震观测资料分析的准确度.

| Abstract: | There is a seismic interference in the extensometer observation in Huailai Seismic Station. The time periods, duration and amplitude of the interference are similar in every year. In this paper, the factors to cause the interference and mechanism of the interference are discussed and analyzed. A method for elimination the interference is also presented. Eliminated the interference with the method, we found a good correlation between the observation records of digital extensometer and earthquakes. The accuracy of seismic data analysis is also improved. |
