很多作者从不同角度阐述过地震过程与破裂过程的相似性。近年来的观察表明,大地震前确有一些前兆现象。但是由于地震现象很复杂,有些现象不易得到反复观测。在地震前发生的现象中,要分辨出那些确为地震的前兆,那些是其它因素的影响,往往要经过多年努力才能弄清。因此,我们试图在实验室中通过测定破裂的前兆来讨论地震前兆
Many authors have described the similarities between the earthquake process and the rupture process from different perspectives. Observations in recent years show that there are indeed some precursory phenomena before the earthquake. However, due to the complicated earthquake phenomenon, some phenomena are not easily observed repeatedly. In the phenomena before the earthquake, it is necessary to distinguish those precursors that really are earthquakes. These are the influences of other factors and often take many years of hard work to figure out. Therefore, we try to discuss earthquake precursors in the laboratory by measuring the precursor of rupture
