摘要
详细介绍了小波分析的基本理论,并将其引入到钢管漏磁探伤信号的分析中,可以去除噪声、压缩数据和检测奇异性,而且为缺陷的定性和定量分析提供了新的判定方法。
The theory of wavelet transform was introduced and it was applied to the signal analysis of magnetic flux leakage. Wavelet transform could he used to separate signal and noise, compress data, and cheek singularity, thereby a new method was provided for the qualitative and quantitative analysis of flaws in magnetic flux leakage testing.
