摘　　要：为有效提高镁碳砖探伤检测中的超声波回波信号的信噪比,研究了小波分析方法对超声波探伤信号的降噪作用.研究表明:小波分析方法不仅能够显著提升信噪比,还能够在局部范围对信号波形进行优化;因此,小波分析方法在镁碳砖探伤检测中具有应用潜力。To effectively enhance the signal-to-noise ratio(SNR)of ultrasonic echo signals in the flaw detection of magnesia-carbon bricks,the denoising effect of the wavelet analysis method on ultrasonic testing signals was studied.The research indicates that the wavelet analysis method not only significantly improves the SNR but also optimizes the signal waveform within localized regions.Therefore,the wavelet analysis method demonstrates potential for application in the flaw detection of magnesia-carbon bricks.
