通过不同环境温度下的简单拉伸试验和应力控制下的低周疲劳试验，找出了环境温度对应力控制下的疲劳行为和疲劳强度的影响。
Simple tensile tests and low-cycle fatigue tests under stress control at different temperature were conducted to investigate the effects of temperature on fatigue behavior and fatigue strength.
低周疲劳常采用寿命分散系数描述结构疲劳强度的固有分散性，而高周疲劳采用疲劳强度减缩系数来描述。
The factor of life scatter is used for depicting the dispersibility of fatigue strength in low cycle fatigue, but in high cycle fatigue is the fatigue strength reduction factor.
