1.金属疲劳
1.loss of strength in something made of metal that could cause it to break
1.Over the past few weeks, aircraft engineers have found they do not know quite as much about metal fatigue as they thought.
过去几个星期，飞机工程师们已经发现他们不像他们所想的那样对金属疲劳了解很多。
2.With no friction between the tracks and the actual train, it will allow it to go at a very high speed without the dangers of metal fatigue.
由于铁轨和列车之间没有摩擦，这使得列车行驶的十分平稳。
3.One thing that does ground old aircraft is the impending failure of their aluminium structure from metal fatigue.
一件事就是飞机铝构造因为金属疲劳产生的故障隐患。
4.All of these actions can put undue stress on the blade and can cause metal fatigue.
所有这些行动可以把不必要的压力，并可能导致叶片金属疲劳。
5.Because there are lots of us for whom repeated stress leading to irreparable metal fatigue to a spiral coil is spring break.
因为有很多人就像螺旋线圈，受到重复的压力后造成无法挽回的金属疲劳，最后弹簧就断裂了。
6.Metal fatigue in vehicle, mechanical, civil, and aerospace engineering will be also introduced in this course.
课程亦将介绍疲劳分析在车辆、机械、航空、土木工程的实际应用。
7.By the 1850s, the steam-engine pioneer James Braithwaite had coined the term "metal fatigue" .
截至十九世纪五十年代，蒸汽引擎的先驱詹姆斯·布雷斯韦特（JamesBraithwaite）已经杜撰了“金属疲劳”这个词语。
8.Excessive torsion on the coupling will cause metal fatigue.
过度地在连结处扭转会导致金属的疲劳、软化。
9.The explosions were attributed to metal fatigue.
爆裂破归因于金属疲乏。
10.Corrosion results in decrease of metal fatigue life and overload can result in prolonging of fatigue life.
腐蚀会降低材料的疲劳寿命而超载则对疲劳寿命有增益作用。
