Therefore, it is an effectivemethod to improve corrosion fatigue property to use the hole cold-expansion technique in the aircraft and other structures.
因此，在飞机和其他结构的关键部位，采用冷胀孔技术是一种提高腐蚀环境下结构疲劳性能的行之有效的方法。

In order to strengthen anti fatigue of cold worked hole, it is necessary to control the magnitude and distribution of the surface residual stress and strain.
为了使冷挤压孔真正起到抗疲劳增寿效果，有效控制孔表面残余应力大小及其分布是至关重要的。

Stand before the hole, hit a cool breeze, the fatigue people to wash the car out.
