| Abstract: | Based on the characteristics of the NMR signal generated in radio frequencyl coil(RF),it is known that the peak value of NMR signal with positive slope of magnetic field change is bigger than that of NMR signal with negtive slope. From the results, a software controled by PC and microprocessor for determining hydrogen content of jet fuels with NMR method was described in this paper. A software flow chart was presented. |
| Keywords: | NMR turning voltage nuclear spin NMR signal standard sample |
