摘要: A surface effect on the behavior of solid-liquid phase transition is studied, considering system a small particle. We calculate dependence melting temperature particle curvature. show that taking account curvature essential in understanding process particles, particular when their radii are order nanometer. The observed non-linear relationship between point and reciprocal radius can be explained satisfactorily by our theoretical model.
