Examples
- The results of quantitative analysis showed that the pre - tension deformation reduced the fatigue crack propagation threshold and increased the crack propagation coefficient , and consequently decreased the fatigue resistance of the part with mechanical damage
定量分析表明：预拉伸变形降低了疲劳裂纹扩展门槛值，提高了裂纹扩展系数，从而使管线在机械损伤的部位疲劳抗力降低。
