英文摘要：

The Zisman equation,the Fowkes equation and the Owens-Wendt equation,which are derived based on the Berthelot geometric averaging rule for the adhesion work of solid-liquid interface,are theoretical foundations of experimental measurements of surface tensions of solid-liquid interfaces.We generalize the Berthelot geometric averaging rule and obtain a generalized expression of the parameters in Zisman equation.We also obtain a generalized Fowkes equation and a generalized Owens-Wendt equation.
