用磁无损检测技术中的巴克豪生噪声法来评估中碳钢的低周疲劳过程．表明：巴克豪生噪声的幅值Ｂ随循环周次Ｎ的增长而下降，并可以利用Ｂ和Ｎ的关系曲线来评估材料的损伤程度．
Bark Howard Noise Method in Magnetic Nondestructive Testing to Assess Low Cycle Fatigue of Medium Carbon Steels. The results show that the amplitude of Barkhausen’s noise B decreases with the increase of N cycles, and the relationship between B and N can be used to evaluate the material damage.
