摘要
从声发射检测过程实施、检测仪器设置和信号处理3个方面来分析声发射检测去噪技术,旨在提高罐底声发射在线检测的可靠性和准确性,为工程实际检测提供一定的指导和借鉴意义。
Starting from the inspection process,instrument settings and the processing of AE signal,the denoising methods for corrosion's AE testing were discussed to improve reliability and accuracy of AE testing and to provide guidance and reference for the practical engineering inspection.
