记录地震 meaning in English
lesson recording an earthquake
Examples
- Between july and november 2002 researchers picked up acoustic signals of unprecedented clarity when recording seismic signals to measure earthquakes and tectonic movements on the ekstroem ice shelf on antarctica ' s south atlantic coast
2002年7月至11月，科学家在南极洲南大西洋沿岸的埃克斯特伦陆架冰地区记录地震信号时，却意外接收到了异常清楚的声音信号。 - The principle of vibrator is to introduce scattered energy to underground in a comparatively long time , and collect the energy through correlation and compress it into a narrow pulse . the portable high - frequency vibrator system , developed by key lab of geo - exploration and instrumentation ( jilin univ ) , ministry of education , generates chirp signal and accumulates energy through a long - time bestiring . according to the characteristics of vibrator , the seismic recorder that operates on - line with vibrator must have these functions as follow : first , it must have the ability of recording a great quantity of data . second , it must have assistant channels to sample reference signal . third , it must have the function of data correlation in real - time
可控震源利用可控的小能量、长时间激发波来实现冲击震源瞬时产生的大能量激发波。在利用可控震源进行地震勘探时,要求地震仪长时间记录地震信号,这对地震仪的采样长度提出了很高的要求。受存储量和数据传输速度的限制,绝大多数地震仪很难对如此大的数据量进行记录,同时,可控震源要求地震仪有两个辅助通道并且具有数据相关功能,目前国内还没有出现满足要求的地震仪产品。
