摘要
Abstract
The principle on the pitting electrochemical noise detected by using wavelet transform was described briefly and the signal of pitting electrochemical noise was analyzed for commercial pure aluminum in 3.5 % NaCl solution. The result showed that wavelet transform could not only obtain the waveform characteristic of pitting signaland system noise in the multi-scale space, but also detect the waveform of pitting electrochemical noise according to the transmitting characteristic of the maximum module of wavelet coefficients, which represented the waveform characteristic.关键词
