The propagation velocity of HeⅡ-HeⅠ interface in pressurized superfluid helium was deduced by use of the two fluid model based on the thermodynamics The result shows that the propagation velocity of He Ⅱ-He Ⅰ interface is less than that of the second sound in irreversible process and is equal to that of the second sound in reversible proces
