The office on the fortieth floor of a skyscraper in the center of new york city is the world he works in 设在位于纽约市中心一座摩天大楼第四十层楼里的那间办公室,就是他工作的小天地。
Dave so became able to move object with the mind force , to discover misterious crimes and to jump with no problem from a skyscraper 他能够以意念移动物体,发现神秘罪行,和安然从摩天大楼跳下来。
" the man who builds a skyscraper to last more than forty years is , a traitor to the building trade . " the words are those of a great american contractor “把一座摩天大楼建造得可以耐用40年以上的人是建筑行业的叛徒。 ”这是美国一个大承包商说的话。
If they are feasible , then the notion of a machine that can build anything from a cd player to a skyscraper in a remarkably short time doesn ' t seem so far - fetched 它们若真能实现,则一台能在很短时间内建造任何东西(从cd唱机到摩天大楼)的机器,将不再遥不可及。
Experimental modal analysis based on ambient vibration is mainly to deal with the engineering problems from with we can hardly achieve the input signals , such as the operational modes of a flight vehicle during the flight or the dynamic behavior of a large - scale structure like an offshore platform , a bridge as well as a skyscraper on which we can ’ t exert a heavy kick 基于环境振动的实验模态分析主要针对一些激励不可测的工程问题,如研究飞行器在飞行中的运行模态,或诸如海洋平台、桥梁、摩天大楼之类难以施加激励的大型结构的动态特性。本文重点研究了随机子空间方法在环境振动模态分析领域的应用。
