当应力增加时，期望的循环数随之减少。
As the stress increases, the expected number of cycles decreases.
一个触点期望承受的挠曲而不损坏的循环数取决于初始应力水平。
The number of deflection cycles a contact can be expected to experience without breaking depends on the initial stress level.
在固定的一组循环数下，对其中每一预定循环数进行不同应力水平的疲劳试验。
Fatigue tests were performed on various alternative stress levels for a group of fixed cycle Numbers.
该曲线族可以转换成相同损伤量下交变应力与循环数关系的等效损伤线族，显示了损伤场全貌。
These curves are then transformed into equivalent damage curve family. Thus the full fatigue damage field is shown .
