| Abstract: | Considering the ignition and combustion characteristics of boron powder, the experiment heat testing of combustion by using combustion improver to ignite the boron is conducted. The uncertainties of combustion heat testing of boron were analysed. The resuh shows that the main factors affecting the uncertainty are the uncertainty of system＇s specific heat capacity and the uncertainty of the combustion heat of combustion improver. When the boron powder burns completely reducing the uncertainty of combustion improver＇s combustion heat is the key factor for improving the measurement accuracy of combustion heat of boron powder. |
