用磁无损检测技术中的Ｂａｒｋｈａｕｓｅｎ杂讯法评估中碳钢的底周疲劳过程，表明Ｂａｒｋｈａｕｓｅｎ杂讯的幅值Ｂ随循环周次Ｎ的增长而变化，可以利用Ｂ和Ｎ的关系曲线来评估材料的损伤特性．
The Barkhausen noise method in magnetic non-destructive testing was used to evaluate the fatigue behavior of the medium carbon steel. It was shown that the amplitude B of Barkhausen noise varied with the increase of N in the cycle. The relationship between B and N could be used to evaluate the material Damage characteristics.
