摘要：
We numerically solve the Cahn-Hilliard equation in two dimensions for very large system sizes and for two different values of the volume fraction phi. We present results for the scaling function of the droplet distribution function and compare it with several different theoretical predictions. We find that for phi = 0.05 the agreement between simulation results and recent theoretical predictions are reasonably good, while none of the existing theories seem to agree well with the simulation data for phi = 0.21.
