All things being equal, which they rarely are, the higher the cyclical stress level on an aircraft structure, the fewer the number of reversals it can withstand before breaking.

所有的事情很少是平等的，飞机结构上的周期性压力水平更高，破碎前它可以承受倒转的数字就更少些。

The U. S. Navy's long-term vision is to deploy distributed wireless sensor networks along with RFIDs to provide a wealth of information about an entire aircraft structure.

美国海军的长期目标是分布式的无线传感器网络与射频身份识别（RFID）同时部署，从而提供关于整个飞机构造的大量信息。

ECONOMIST: Aircraft fatigue

What makes aircraft fatigue such an dark art is that, unlike standard tests done in a laboratory, an aircraft's structure has to endure a complex, mostly random, set of static as well as cyclical stresses when in service.

Training doesn't just involve teaching someone how to structure an aircraft loan, write nifty software or even hew to company policies.
