将三维荧光谱数据绘成三部分：1.激发波长，发射波长与荧光强度的关系；2.对应的指纹图；3.荧光强度分别于发射波长与激发波长的二维关系图。另外利用小波阈值去噪得到的效果，便于观察。-The data is plotted as three-dimensional fluorescence spectra of three parts: an excitation wavelength, emission wavelength and the relationship between fluorescence intensity　2 corresponding fingerprint　3 fluorescence intensity at each emission wavelength and excitation wavelength of the two-dimensional diagram.. Another advantage of wavelet thresholding get results, easy to observe.
