But steel alloys subjected to cyclic stress levels below their endurancelimit rarely fail as a result of fatigue.
但是在钢铁合金的耐用度限制下，作为疲劳的结果，它们经受周期压力级别很少失灵。

Care should be taken when using the idea of an endurancelimit as a "safe stress" below which fatigue will not occur.
用疲劳极限作为低于它将不出现疲劳的安全应力时，必须要注意。安全应力时，必须要注意。

In this paper, contact endurancelimit diagram of 45 normalizing gear is obtained from contact fatigue teste on 8 pairs of CATT gears. It is worthy reference for a calculation of gear design.
