摘要
在涡流检测中 ,扰动磁场的分布比线圈的阻抗能够更好地反映缺陷信息。研究缺陷参数与扰动磁场的对应关系 ,通过扰动磁场的分布识别缺陷。
The perturbed magnetic field due to a defect gives more information about the defect than the coil impedance change. The relations between the perturbed field and defect parameters are studied. A defect can be reconstructed by perturbed field.
