2.3 | Spectrum analysis
After randomly numbering the spectrum data of all cases, the phase and
baseline were corrected by the software of the machine itself, and the
integral value of each peak was calculated; the integral value of each
peak corresponding to each compound was determined according to the
chemical displacement, and the integral value ratio was obtained by
comparing its integral value: Cho / Cr, Cho / NAA, Cr / NAA, etc.
