Maybe they could reverse - engineer a fly to make a robotic device that could reconnoiter5 dangerous places , such as earthquake zones or collapsed mines 也许他们能以还原工程的方式来解析苍蝇，进而制造出一种机器人装置，用来勘察地震区或塌陷矿场之类的危险区。
Daqing city , on the whole , belongs to the weaker part in the northeast earthquake regions , but the earthquakes on a little scale occurred more frequently since 1970 大庆市属于东北地震区地震活动相对较弱部分，没有中强震的历史记载，但1970年以来地震观测资料表明，大庆及邻区现代小震活动相对频繁。
This paper have been different structure form increasing storey discussed by analyzing the applying of jacket frame in the earthquake and introducing some examples of the different regions 通过比较，提出采用层间桁架结构的外套增层结构方案。对此类增层方案在地震区的地震波作用下的抗震反应进行分析。
It is show that non - demoulding shear wall in which the cold - draw steel wire is taken as reinforcement has great capacity of resisting seismic and quality in the area of seismic 试验及分析表明：免拆模板剪力墙墙片单元在墙片单元之中使用冷拔钢丝网片作为配筋时具有良好的抗震性能，可以满足地震区的设计要求。

The structural system has considerable energy - dissipation capacity , so can be generalized and used in medium seismic zones . due to exerting prestress , the structure has satisfiable self - centering capability 结果表明，该结构形式若设计得当，是可以形成梁铰耗能机构及整体破坏机制的，且该结构形式具有一定的耗能能力，可以在中等地震区推广使用。
Hada mountain embankment dam is located at strong motion earthquake area with 7 degree . it is a sand - fill dam with clay core , stability of the dam under earthquake and the preventive of foundation liquescence is very important for the dam design 哈达山土坝是位于七度地震区，坐落在厚覆盖层上的粘土心墙砂壳坝，坝体的抗震稳定、基础的抗震液化是本工程的技术关键问题。
With the functional diversification of tall building , the tube structures with transfer storey have been widely used in seismic zones . the level of transfer storey is higher and some new styles of transfer member , such as transfer bracket , have been used recently in tall buildings 随着高层建筑向多功能发展，带转换层简体结构在地震区得到了广泛应用，转换层位置逐渐增高，近年来还出现了“搭接柱”式新型转换层结构形式。
Appling the hollow shear wall to multi - story and sub - high rise residences , these can be come into being that include reducing self - weight , stiffness , earthquake action , and improving ductile , saving material and energy , so building ' s integration economy target can be fallen 将这种墙用于地震区的多层和小高层房屋，可以减轻自重，减小刚度，降低地震作用，提高延性，节约材料，并且节能效果好，降低了房屋的综合经济指标。
This paper is concerned with the evaluation of seismic capacity of prefabricated prestressed concrete skeleton structure ( ims system ) . the elasto - plastic time - history analysis and the push - over analysis are performed for this purpose . in order to promote the ims system ' s use in the area of high seismicity , systematically research has been made to study its dynamic response and damage mechanism under horizontal seismic action 本文采用弹塑性时程分析方法及静力弹塑性分析方法对预应力板(梁)柱体系抗震能力进行了评定，较系统的探讨了该体系在地震作用下的动力反应及破坏机制，旨在促进该体系在地震区的推广和使用。
