厦门地震台3066型记录仪故障现象及分析

Phenomena and Analyses of Instrument Failures of Type 3066 Pen Recorder at Xiamen Seismostation

厦门台垂直摆模拟记录曲线接连出现几次畸变现象,通过对比分析数字化记录和模拟记录曲线,查找干扰原因,认为很可能是静电对模拟记录仪的干扰影响。

It is the responsibility of observers to assure that instrument runs normally and continuously. Aberration appeared in analog record curves of the vertical pendulum of Xiamen Seismostation in succession recently. In this paper, the cause of interference is investigated by comparing digitized records and analog recorder curves, and it is believed the interference probably arises from the effect of static electricity upon the analog recorder. But there also are probably other interference factors, which need further observation and study.
