摘　　要：分析了磨削非正常接触及其时空敏感性,阐述了以酸洗-磁粉探伤复合检测来显示裂纹和磨削变质层关系的方法,提出通过对磨削宏观痕迹分析来寻找真实磨削接触条件的方法,并介绍了一些典型的磨削非正常接触案例。The abnormal contact and time-space sensitivity of grinding are analyzed,the method of displaying relationship between cracks and grinding degenerating layer by pickling-magnetic particle testing combined detection is expounded.The method is proposed for searching real grinding contact condition by analyzing macroscopic grinding trace,and some typical grinding abnormal contact cases are introduced.
