摘 要:
用试验的方法分析裂纹的深度、裂纹与磁化结构行进方向之间的角度以及平行裂纹的间距等参数对裂纹漏磁检测信号幅值的影响,并给出裂纹深度、角度与裂纹漏磁检测信号幅值的关系曲线。试验结果为裂纹漏磁检测与评价提供了参考依据。[著者文摘]

Abstract:
The experiments are applied into analyzing the parameters' influence on the crest values of test signals ,just as the depth, the angle of incline and another cracks in sight of it whether or not . And the curves are given. The outcome may offer the frame of reference in practical cracks' MFL testing.[著者文摘]
