These curves are then transformed into equivalent damagecurve family. Thus the full fatigue damage field is shown .
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。

From the curves we can see that most of the experiment results are above the linear cumulative damagecurve, it indicates that the steel P91 is negative interaction under the condition of this thesis.
The inversion of its yield curve last happened two weeks ago but, unlike then, purchases of Rome's bond by the European Central Bank on Tuesday failed to undo the damage.
