结果：三组完全流产率、孕囊排出时间、出血时间及月经复潮时间差异无显著性；a组妊娠小于6周者完全流产率与妊娠6周～8周者相比差异有显著性；疗程短者出现副反应小，三组差异均有显著性。结论：米非司酮服用时间越短，其胃肠反应与头晕乏力等副作用越小；a组具有用时短、疗效确切、副作用小等优点，尤其对孕周小于6周患者流产效果好。

Abundance of salt-alkaline megatherm Classopollis-Ephedripites assemblage in a limited time illustrates a short duration of dry hot climate by latest Cretaceous. Such extreme climatic change and ecologic overturn are possible causes of the dinosaur extinction in the study area. Other factors, such as asteroid impact and large volcanic eruption triggering global mass extinction caused the regional climate change.

嘉荫群上部渔亮子组中膏岩层和耐高温、抗盐碱的克拉梭粉-麻黄粉组合在短时间内的大量出现，说明晚白垩世末期出现有短暂的干热气候，这种气候的突然转变以及伴随的生态系统的紊乱可能是嘉荫地区恐龙大量死亡的重要原因，但不排除诸如天外星体碰撞地球、大规模火山喷发等引发白垩纪末恐龙全球灭绝的因素，后者更可能是引起气候变化的直接因素。

The properties of blast loading are that it is highly impulsive, exhibiting high-pressures but lasting for a very short duration. The propagation process of shock wave produced in steel-concrete composite beams subjected to blast loading is very short. And there is only small deformation for the beam during the time of the propagation process of wave.

由于爆炸荷载作用时间短、超压峰值大等特点，当爆炸荷载作用于钢－混凝土组合梁上时，将在梁内产生冲击波，冲击波在钢－混凝土组合梁内的传播过程极短，并且在冲击波的传播过程中梁的变形很小，因此，可将冲击波在梁内的传播过程进行独立分析。
