摘要：

The correlation between local potentials and the excess Gibbs free energy G is discussed in mean field approximation. Landau-type solutions with quantum corrections apply in the displacive limit. The kinetic rate laws for continuously variable state parameters are found to follow rate laws in which the driving force is partial derivative G/partial derivative Q where Q is the macroscopic order parameter. The crossover between these continuum rate laws and the Glauber rate law is explored by molecular dynamics simulation.
