Abstract:: 　T he heat values under constant volume (Qv)of edible soya oil were measured with WZR-1Amicrocomputer calorimetry .After the benchmark substance were accurately quantified and the heat capableof the calorimetry was determined.The capsule with sample was put into the oxygen bomb, the sample wascompletely combusted in oxygen bomb with high pressure pure oxygen.These record of time and thechangely of calorimeter temperature were analyzed with the self -designed data treatment system of oxy-gen bomb combustion.This method was proved to be accurate , simple and convenient to be used in routineanalysis.
