对于中值寿命，轮盘和光滑试样的寿命之比仅为1.2倍。
For the median LCF life, the ratio of the experimental life to the predited life is 1.2.
研究了硫酸阳极氧化和铬酸阳极氧化工艺对LY 12 CZ板材、LC9CS棒材在中值寿命区疲劳强度的影响。
This paper studies the effects of the sulfuric acid anodizing and chromic acid anodizing on the fatigue strength in the intermediate value life zone of LY12CZ plate and LC9CS bar.
因此在第二章，本人用半参数方法提出了协变量测量有误差时的中值回归模型，用它来估计寿命变量的中值。
In the second chapter, I propose semi-parametric estimate to get median regression models with the measured error margin and use it to estimate the mediant of survival data.
