The Rayleigh fractionation model is first deduced by the principle of dynamic reaction, which indicates that Rayleigh fractionation can be explained by dynamic characteristics of isotopic molecules in the reaction process. Subsequently, the analytic expression of evaporation line is deduced under equilibrium condition in the open systems of Rayleigh mode, which shows that it is an exponential form. The simulation results show that the slope of the evaporation line under equilibrium condition changes with the temperature that the higher the temperature is, the smaller the slope is and thus the higher the degree of enrichment is. This research can provide reference basis for better understanding the dynamic characteristics of isotopic molecules in evaporation process. |
