| Abstract: | The infrared absorption spectra of the rice flour and several kinds of milk powder were determined respectively by attenuated total reflection-Fourier transform infrared spectroscopy（ATR-FTIR） so as to compare the contents of fat,protein and carbohydrate in different measured samples with each other by calculating the ratio of peak area.And it is applied as a part of the open and designing IR experimental teaching,which improves the students＇ comprehensive and innovative ability to solve practical problems,and better teaching effect is obtained. |
