| 摘 要： | 成都台网记录中心接收的地震波信号有EDAS-24L和EDAS-IP采集器采集的波形,还有RSDA-1采集器采集的波形。汶川8.0级主震发生时,全川台网采集到的波形大部分被限幅。但由于使用的数据采集器不同,地震波被限幅的形状和幅度都不一样。EDAS-24L和EDAS-IP采集器采集的波形呈"振荡限幅"特征,而RS-DA-1采集器的波形呈"平坦限幅"特征,本文解释两种限幅特性的原因,并说明RSDA-1采集器波形"平坦限幅"的意义。

| Abstract: | The waves were recorded in Chengdu Recording Center by the EDAS-24L and EDAS-IP acquisition devices addition to RSDA-1 acquisition devices.Since the 2008 Wenchuan 8.0 Earthquake is a huge seismic event,the amplitudes of seismic wave recorded by all seismometers in Sichuan Province are limited.The types of the acquisition device are not the same type and the figure and amplitude of wave from acquisition devices are not entirely same.The waveforms from both EDAS-24L and EDAS-IP Acquisition Device are of chara... |
