磁痕 meaning in English

magnetic particle indication
magneticparticleindication

Abstract : it was deduced that the shapes of magnetic particle indicationsof point - type defects on workpiece surface depended on the resistance of carrier medium , and their dimensions depended on the volume of the defect equivalent cuboid , the magnetising characters of workpieces and magnetic particles , the strength of magnetic field , the lengths and sections of magnetic particles and the resistance character of carrier medium
文摘:推断出工件表面点状缺陷磁痕的形状取决于磁粉载体的介质阻尼力，磁痕大小取决于缺陷等效长方槽的体积、工件和磁粉材料的磁化特性、磁场强度、磁粉长度和横截面积以及载体介质的阻尼特性等。
