摘要：
it is demonstrated that a simple model, free of any adjustable parameter, can be developed to predict the free energy of a crystal-liquid interface sigma(sl) based on the Gibbs-Thomson equation and a model for the size-dependent melting temperature. This model has improved Turnbull's empirical equation. In the model, sigma(sl) depends on not only the melting enthalpy of crystals, but also the vibrational component of the overall melting entropy of the crystals. The predicted values of sigma(sl) for different types of crystals, such as true metals, meta metals, semiconductors, ionic crystals and organic crystals, are confirmed by available experimental results in the experimental error range.
