| 摘 要： | 分析了海南前兆台网水位仪对苏门答腊M_S 8.7地震和我国四川汶川Ms 8.0地震的高采样率水震波记录情况,从中可较明显地看到地震波引起的井水位详细变化,但也存在水震波的丢头、仪器时间存在误差,第一代仪器水震波相互覆盖等现象,提出了在水位仪中增加在线缓存记录、自动定时校时功能等改进建议。

| Abstract: | The high sampling rate water-seismic waves about Sumatra-Andeman strong earthquakes and Wenchuan earthquake recorded by water-level meter of Hainan digital seismic precursor network were analyzed. The detailed variations of well water-level caused by seismic waves can be distinguished from the water-seismic waves. But there were some problems, such as the heads of water-seismic waves were missed recording, time errors of water-level meter relatively great and water-seismic waves recorded by the first generation water-level meter sometimes were covered each other. The some improvements： such as adding function of data online cache and automatic correcting time in water-level meter were put forward. |
