用热退磁和交变场退磁方法对59个采点的619块样品做了磁清洗处理。
We have carried out magnetic cleaning for 619 specimens from 59 sites by A. F and thermal demagnetization.
该曲线族可以转换成相同损伤量下交变应力与循环数关系的等效损伤线族，显示了损伤场全貌。
These curves are then transformed into equivalent damage curve family. Thus the full fatigue damage field is shown .
