| 摘要: |
| 本文通过实验得出：在测定渗碳钢接触疲劳极限时，只要正确判断试样是由于次表层萌生裂纹而失效的，那么Miner 线性累损伤理论是可以应用的。本文提出不同渗碳工艺处理相同材料之 σ-N曲线之间存在着一种平移关系这一假设，并给出了应用这种关系求疲劳极限的方程。 |

| The Study of Application of Fatigue Summation Damage Theory |

| Abstract: |
| This paper makes the first step to study the app1ication of fatigue summation damage theory by subaividing the manner of crack generation.
The study on this field had been limited in using different formulaes to modify the contradiction in test. It proves that Miner's linear summation damage theory can be used for contact fatigue test，if the spacemen fai1ure is in the second surface crack generating failure. |
