The author made a more accurate short-term prediction before the earthquake, based on the anomalous change of cruststress.
根据地应力异常变化，作者曾作了较准确的短期预报。

In this paper are described first the differential equation and finite element formula for fluid migration under the action of cruststress in a porous rock.
首先叙述了地应力作用下空隙弹性介质中流体运移的基本方程及由基本方程推导的有限元公式。

In the meantime, the inevitable relationship between the fault motion and the out-of-balance of the cruststress caused by underground coal extraction is analyzed.
