英语释义

1. a law in physical chemistry: the number of degrees of freedom of a system in equilibrium is equal to the number of components minus the number of phases plus the constant two (as in the system ice -liquid water- water vapor consisting of the one chemical component water and its three physical phases there are no degrees of freedom and the system can exist at only one temperature and pressure)
