%X Based on the static-friction model for solid-liquid-vapor contact line suggested by Adam and Jessop,one can calculate surface-tension coefficient of solids from the data of wetting angles, but the results depend on the friction condition adopted. Using the data reported on stainless steel and polypropylene samples as examples, we have compared the surface-tension coefficients given by the Mises yield condition and Amonton's friction law. It is found that only the latter possesses always the Wenzel behavior which claims an increase of surface-tension coefficient with surface roughness, as well as total wetting condition, namely receding angle vanishes when the difference of solid-liquid and solid-vapor coefficients equals that of liquid-vapor. This shows that the Amonton's law seems to be more reasonable for describing the static friction of contact line.
