In order to summarize the standard conditions of the mid-infrared absorption spectrum for tea samples, the spectrograms are analyzed with the method of uncertainty in this paper. In the work, the absorbance of every absorption spectrum is averaged firstly to get the value xi, X̅ named true value has been get by averaging the obtained xi of the six spectra in the same condition. As a result, the standard...
