从华北３７次Ｍ≥６．０地震前的地震活动图象异常，以及１９５４～１９９２年首都圈地壳形变图象研究中，提炼出强震前的异常特征；对强震前的地震活动图象异常与地壳形变异常进行对比分析．结果发现：①强震前出现地震活动的增强与地壳形变速率的增大；②震前数年环绕强震震中出现孕震空区与形变空区；③在图象动力学参数方面都表现出信息维的减小，表明地壳形变局部化随着时间而增加，是反映强震孕育阶段的重要现象和参量．最后，应用非均匀介质中非均匀坚固体孕震模式，对强震前地震活动图象与地壳形变图象异常物理机制给予了统一解释．
The anomalous features before the strong earthquakes are extracted from the anomalous seismicity images before 37 M≥6.0 earthquakes in North China and the crustal deformation images from the capital area in 1954-1992. The seismic activity images before strong earthquakes Abnormalities and crustal deformation anomalies were compared. The results are as follows: (1) The increase of seismic activity before the strong earthquakes and the increase of the crustal deformation rate; (2) The occurrence of pregnant lost and vacant areas in the epicenter of strong earthquakes several years before the earthquake; (3) The reduction of information dimension indicates that the localization of crustal deformation increases with time, which is an important phenomenon and parameter reflecting the gestation phase of strong earthquakes. Finally, using the non-uniform medium solid insolation model, we give a unified explanation of the anomalous physical mechanism of seismic activity image and crustal deformation before strong earthquakes.
