Geophysicist Mark Zumberge at the Scripps Institution of Oceanography is developing a new breed of seismometer to get a better look inside the Earth. 斯克里普斯海洋研究所的地球物理学家马克•藏伯格正着手开发一种新的地震仪,从而更细致地观察地球内部情况。
Zumberge said a conventional seismometer records how its mass is displaced by these waves of seismic energy with electric circuit boards. 藏伯格称,常规地震仪采用电路板记录重物受地震波影响的振动情况。
We've come up with a way, using optical fibers, to bring laser light to and from the seismometer, to make very precise measurements of the vibrations of the mass in our seismometer. 我们想出了一种新方法,通过光导纤维将激光导入和输出地震仪,从而精准地测量重物的振动值。
Well here we're looking at the vertical component from the seismometer, and this is just the background motion. 我们在看测震表上的竖直部分,这只是背景移动。
