| 摘 要： | 为了满足概率疲劳分析的需要,推导出了应力比Ｒ等于常数时细节疲劳额定值（ＤＦＲ）与其它疲劳参数之间的解析表达式,从而使Ｓ－Ｎ曲线解析化。通过焊接件的疲劳试验和分析证明了其有效性和实用性。

| Abstract: | o satisfy the needs of probabilistic fatigue analysis,on certain assumption conditions,the relationships between Detail Fatigue Rating(DFR)and other fatigue parameters under con- stant stress ratios are obtained. Analysis of the fatigue test results of welding specimens shows that the relationships are correct. |

| Keywords: | probability-fatigue fatigue tests weld strengths |
