| Abstract: | The multi-resolution character of continuous wavelet transform(CWT) is applied to analyze the frequency character of Mn~(4 ) ion catalyzed oscillating chemical system,its frequency values are extracted successfully.The results show that the oscillating chemical system has multi-frequency character.The ability of extracting the frequency values of complex system for this method is superior to traditional Fourier method. |
