摘　　要：通过北京周围地区中强地震前后介质Ｑ值、剪切应力和小震（Ｍ＿Ｌ≤３．０）震源参数的变化的研究，给出一种中强地震短临预报的新方法。In this paper,we studied the changes of Q value in crust,shear stress and sourceparameters of small earthquakes(M_L≤3.0) before and after moderatel earthquakesaround Beijing area,and gave a new method of short term and imminent prediction formoderate earthquakes.

关 键 词：剪切应力 Q值 短临预报 震源参数
