摘要：

An expression for the time rate-of-change of the thickness of the surface phase was derived using a simple approximation. It was shown that in the asymptotic limit of long times, the thickness of the end phase is linearly proportional to time, while the coarsening rate is proportional to the square of the compositional strain and inversely proportional to the film thickness.
