摘　　要：漏磁检测的量化问题是漏磁检测应用推广需要解决的关键问题。对缺陷漏磁场特征与缺陷长度的关系进行了研究,表明缺陷长度是影响漏磁检测缺陷量化的重要参数。A key issue, which influences the applications ol magnetic flux leakage testing, is defect quantification. The relationship between characteristics of defect leakage field and defect length was investigated. Testing results show that defect length is an important parameter needed to consider in quantifying defects
