 Mathematical fitting of the experimental data suggests that the shrinking sphere model is the most adequate to describe the carbochlorination mechanism of chromium oxide and that is controlled by the chemical reaction. Mathematical fitting of the experimental data is discussed. If these corrections are not possible, then the choice of mathematical fitting method should be constrained to provide results which are consistent with physical-theoretical considerations of the energy-efficiency relationship being modeled. The two relaxation processes have been resolved by mathematical fitting using numerical approximations. The mathematical fitting indicates a lineal evolution for the three components where r is the regression coefficient of fitting. 更多 Based on the analysis of physical and geometric features of turbine characteristics, a flow and efficiency-characteristics fitting model for variable-nozzle turbines is provided.
