Proper calculating model w as selected, and calculating softw are for thermal properties of mult-i component gas w as compiled. T he calculated results by the softw are w ere compared w ith the experi- mental values. Results show that the set up mixed model is reasonable and reliable. Using program to cal- culate the thermal properties of mult-i component gas is readily , reliable, and has high accuracy.
