Based on rectangular dislocation theory in an elastic-viscoelastic layered medium, we have simulated the co- seismic deformation and gravity change with gravitational effect considered. The pictures show that the absolute gravity measuring point is beside the extremum of coseismic gravity change, and the numerical value reaches 25.02 x 10-Sm. s-2. After a discussion about the gravity changes before the earthquake and the coherence consistency between two FG-5 absolute gravimeters, we think that the measured value 27.2 × 10^-8 m· s^-2 at Yushu station is coseismic gravity change. It＇s coincident with the simulation results based on dislocation theory. Therefore it is a good tool to test the near-field changes found by dislocation theory.展开更多

The research design mainly involved student participants from three universities in China. The findings of this study may suggest that the ability in writing tested could be generally reflected by the internal sub-processes; the test-takers' translating ability variance can be marginally statistically reflected; the sub-processes such as topic and genre modifying, organizing, translating, reviewing may have more effect on score gains than some other sub-processes. In this sense, TEM8E can be generally regarded as a test reflecting the writing ability, but it needs improving.展开更多
