Dropping out this time is the track athlete who won over fans in Beijing: Jamaican Usain Bolt, who sprinted to three world records at the Games and has continued breaking them since.
这次未能参赛的是在北京奥运会上一举成名的牙买加选手博尔特(Usain Bolt)。他在比赛中刷新了三项世界纪录，并在此后的赛事中延续了这种势头。
Bolt parameters of the track tunnel were simulated by using the finite software ANSYS in order to provide a theoretical basis for designing support parameters.
为了给现场锚杆支护参数的设计提供理论依据，采用有限元软件ANSYS对该轨道巷锚杆的支护参数进行研究。
Based on the flexible array sensors, using hierarchical design and inside-bolt linking structure, we developed the mobile digital-track and its system software.
