摘要
根据磁偶极子理论,证明由于工件形状、磁化方式和沟槽深度的不同,工件表面沟槽深度与其所产生的漏磁场会分别呈“直线律”和“指数律”关系。
It is proved according to the theory of magnetic dipole that there will be 'linear law' or 'exponential law' between slot depth in the workpiece surface and the magnetic leakage field produced by the slot due to the differences of test block figures, magnetizing types and slot depthes.
