摘      要：The field and source are two important branches in seismology and earthquake *** this paper,we use a computer model to study the relation between the field and the source in earthquake *** our modeling,a network of nonlinear elements is used to simulate seismic activity of seismic zones in a seismotectonic *** strain rate is enforced on the boundary of the model,cyclic seismic activity,quasi-periodic variation of stress field intensity,and strain energy are observed with high and low *** is a main seismicity area in seismic cycles,and the main seismicity area shows the spatial migration during different seismic *** the precursory area is related to high element stress,it is found that the development of precursors in our model is quite *** certain relation between the precursors and earthquakes has been *** show different characteristics in the seismic quiet period and active *** of the seismic zones in the system
