Using this model, the stress adjustment in the whole of the Southwest China region in response to the stress change due to strong earthquake occurrence is studied. The preliminary result shows that many strong earthquakes occurred in areas where the stress heightened after the last strong earthquake. So, the finite element model set up in this paper is useful for judging the regions where strong earthquakes are likely to occur in future.展开更多

From activity theory point of view, meaningful learning is an active, conscious, constructive, and socially medicated practice that includes reciprocal intention-action-reflection activities. This paper aims to try to give a MOOC learning activity design model in grammar teaching which tries to offer a reference for the MOOC teaching in grammar lesson.展开更多
