摘要：

The influence of the spatial variation of the scalar order parameter on the anchoring energy is analysed. It is shown that if the nematic average orientation is forced to change too rapidly, a surface melting is expected. Furthermore, by considering two typical situations in which the surface scalar parameter is different or equal to the bulk one, the renormalization of the anchoring energy is estimated.
