This has turned the three hours of practice on Grand Prix Fridays into highly valuable track time, as it is now teams' only real opportunity to track test in-season developments.
这就使得大奖赛中周五在赛道上三个小时的练习赛变得逾足珍贵，因为这三个小时就是车队在赛季中进行在赛道上测试开发的唯一机会。
Fortunately I consider myself a driver who does not need a lot of track time to be on a good pace straight away.
幸运的是，我认为自己是这么一个车手——一个不需要太多圈数就能熟悉一条新赛道的车手。
Testing is currently banned once the season has started, with limited track time during the European winter as part of cost-saving measures.
目前只要赛季一开始便不得进行测试，作为节省资金的一部分只能够在欧洲的冬天在有限的赛道上进行测试。
In this paper, the fundamental problems in the calculation of transverse vibration of train bridge and train track time varying system are expounded.
本文论述了车桥及车轨时变系统横向振动计算中存在的根本问题。
In light of recent disappointments, Williams will be out to make the most of available track time, with technical director Sam Michael having promised improvements to the car for Monza.
从最近的沮丧来看，威廉姆斯车队将充分利用可用的赛道时间，而技术总监山姆·迈克尔也许诺赛车会在蒙扎有所进步。
It can overcome the effect of bad data on parameter estimation, and has strong robustness, and can track time-varying parameters because the discontinuous recursive computation was applied.
该方法由于采用了间断迭代，因此可以克服坏数据对参数估计的影响，且具有较强的鲁棒性，又可以跟踪时变参数。
The transverse track irregularity is mostly treated as the exciting source of transverse vibration of train-bridge (or track) time-varying system at home and abroad.
国内外在列车-轨道时变系统横向振动计算中，大多采用轨道横向不平顺作为列车-桥梁(轨道)时变系统横向振动的激振源。
