摘　　要：根据破茬圆盘刀点腐蚀声发射信号的特点,提出了较适合于声发射混合信号的处理方法,即小波分析与ICA相结合的方法,对破茬圆盘刀点蚀AE信号进行处理;并在Matlab环境下编制了相应的ICA软件,使独立分量分析更加直观、可靠。The signal separation method which was more suitable for acoustic emission had been proposed. This method was to combine wavelet de-noising with independent component analysis in order to de-noise and separate acoustic emission signal on disc sickle corrosion. Independent component analysis software had been edited by Matlab. This mad the independent component analysis more intuitive and reliable.
