摘要
本文简单介绍了有线地震仪产生延迟的主要原因,详细分析了408UL仪器和其它仪器对延迟的校准及得出第一个样点的方法,最后得出处理方法不同会造成同步精度不同的结论。
The paper briefly introduced the main reason of delay the wire seismograph produced,analyzed in detail the method that the 408 seismograph and other seismographs calibrated the delay and got the first sample and finally concluded that different processing method resulted in different synchronous precision.
