| Abstract: | The crystal transition temperature of phase stabilized ammonium nitrate was determined by differential scanning calorimetry（DSC）.The uncertainty components caused by random factors,sample quantity,instruments,and selecting different baseline points during the determining course were discussed.It is calculated that the synthesis standard uncertainty for the crystal transition temperature of phase stabilized ammonium nitrate determined by DSC is 0.18℃,the expanded uncertainty is 0.36℃. |
