摘要
讨论当前钢材硬度涡流无损检测面临的两个难点 ,提出了一个新的检测方法 ,即使用Fourier系数的均方差构成决策图 ,并用多频涡流的方法 。
Two difficulties in eddy current nondestructive testing of steel hardness were discussed. A new method was put forward that the decision plane formed by the average square error of Fourier coefficient and multi frequency eddy current method were used to classify steels by hardness.
