摘要：

The thermodynamic approximate-expression for liquid-solid interface free energy which has its origin in the loss of configurational entropy due to the adjustment of the liquid to a boundary was derived. Triangular-square-pentagonal lattices were proposed for a structural model of the liquid-solid interface. Calculated values from the thermodynamic approximate-expression and the interface structural model showed a fair agreement with previous experimental data.
