复发间隔(recurrence interval)是指同一活断层段上相继发生的2次震级相近地震之间的时间间隔。不同震级地震的复发间隔时间不同,震级越高复发间隔就越长。
在我国的北京西北地区,存在着一些离逝时间远大于复发间隔的活动断裂(段)。
In northwestern Beijing (China), there are some active faults or segments with elapsed time much greater than the recurrence interval.
因此,基于断裂带整体强震复发间隔分布的中长期危险性概率评估仍然面临一定的困难。
Therefore, the probabilistic assessment of middle - and long-term seismic hazard based on the strong earthquake recurrence for entireties of active fault zones still faces some difficulty.
结论雷公藤多苷可明显促进顽固复发性阿弗他溃疡愈合,延长复发间隔期,减少复发次数。
Conclusion TG could promote healing of stubborn RAU, extend the recurrence interval and reduce relapses.
