摘要
对边界的存在对残余应力无损磁测法测量结果的影响作了仔细地研究 ,进行了边界效应影响的理论推导 ,得出了修正测量数据的依据 ,并在此基础上 ,讨论了探头测距对测量精度的影响 。
We have studied the results of nondestructive magnetism of residual stress with the effects of boundary. We carry out the influence of boundary-effect in theory. We have got the gist to modify the measuring data. On the basis, we have discussed the distance of probe and its influence on measuring precision ,and found a new method to prove measuring precision.
