The frame 's fatigue strength distribution has been obtained by calculating the experimental result of material fatigue test and has been described by means of two regression curves.

构件的疲劳强度分布是由材料疲劳强度试验的结果经统计处理后，用两条拟合曲线来描述的。

The results showed that the statistical characteristic for static strength and residual fatigue strength of carbon epoxy laminates could be properly described by this distribution model.

结果表明，这一分布模型能够更全面地描述复合材料层板静态强度和疲劳剩余强度的统计特性。

It is recommended that new statistical methods should be used to evaluate the size, distribution of inclusions and its effect on the fatigue strength of the steel.

建议采用新的统计方法评估钢中夹杂尺寸、分布及其对疲劳强度的影响。
