| Abstract: | The combustion heat under constant volume （Qv） of eight samples were measured with WZR-1A microcomputer calorimetry. After the benchmark substance were accurately quantified and the heat capable of the calorimetry was determined. The capsule with sample was put into the oxygen bomb ,the sample was complete combusted in oxygen bomb with high pressure pure oxygen. These record of time and the change of calorimeter temperature were analyzed with the self-designed data treatment system of oxygen bomb combustion . This method was proved to be accurate,simple and convenient to he used in routine analysis. |
