天文学家依靠望远镜才能对浩翰无边的宇宙繁星进行观察和研究,对地震学家说来,地震仪器的观测就像天文望远镜一样,是必不可少的工具,但还有其独特的要求,即地震仪的安装位置及其相互间的联系,都对整个地球的地震活动性的研究起着很重要的作用和影响。因此,在全世界建立一个全球性的地震台网不间断地监视着地震的活动性, Astronomers rely on telescopes to observe and study the vast universe of starry stars. For seismologists, seismological observations are just as essential as astronomical telescopes, but their unique requirements, namely, The location of the seismographs and the connection between them all play an important role and influence on the seismicity of the whole earth. Therefore, the establishment of a global seismological network around the world to continuously monitor the seismic activity,
