Abstract：Combined with time accumulated resolution and space resolution the SU-HTRS(T/S) set has been realized at Shanghai University. It is impossible to avoid noise at high temperature, so different mathematic methods, such as Savitzky-Golay method, FFT and wavelet methods have been adopted for denoising. For various noise levels, the effects of three methods on the peak location, intensity and covering area as well as the smoothing degree of the reduced spectra were analyzed. It can be concluded that Savitzky-Golay method is simple and quick, while wavelet method offers the best results in denoising process.
