摘　　要：This paper is the second one of the serial papers about the study on strike slip earthquake-generating structure in the interior of the Chinese mainland. In the first part of the paper,the deformation field model of strike slip earthquake-generating structure is elucidated.It puts forward that a strike slip fault is not dominated by horizontal displacement everywhere along the whole belt,its deformation characteristics is different from section to section, only the central main body shows strike slip feature,the two ends take vertical deformation as the major feature.In the second part,through the discussion of deformation field characteristics about strike slip earthquake-generating fault for several clearly investigated large earthquakes with M≥7.0 that occurred recently in the Chinese mainland, it is further confirmed that although each of these earthquakes possesses its own complicated features,they also share the common feature that the earthquake-generating faults have the deformation field characteristics similar to those of the above-mentioned strike slip earthquake-generating structure.This paper is the second one of the serial papers about the study on strike slip earthquake-generating structure in the interior of the Chinese mainland.
