| 摘 要： | 介绍了周至深井井孔概况和水位观测的仪器设备配置，通过对2000年10月6日日本本州7．3级地震的水震波数字化记录的频谱分析，与陕西数字地震台网同一地震事件进行对比研究，结果表明，周至深井可以记录到周期大于2s的水震波，对地动位移的放大倍率约为200倍，带宽大于DK-1地震仪和FBS-3地震计，相当于一台深井宽带地震仪。

| Abstract: | The general situation of deep borehole and apparatus for water-level observation at Zhouzhi Seismic Station are described. The spectrum of digital recording of seismic water-level fluctuations of Japan Kyushu earthquake with magnitude 7.3 on October 6, 2000 obtained at Zhouzhi Station is analyzed. A comparative study of it with the digital seismic wave recording of the same event from the Shanxi Digital Seismograph Network is made. The results show that the water-level detector in Zhouzhi deep borehole can record seismic water-level fluctuations with period greater than 2 seconds; amplification of ground displacement in the borehole is about 200 times. The bandwidth of the water-level detector in the borehole is greater than that of DK-1 seismograph and FBS-3 seismometer, equivalent to a broadband seismograph in a borehole of 2500 m deep. |
