摘要：
The effect of noise on the average orientation imposed by the surface treatment on the bulk properties of a nematic liquid crystal is evaluated. The general solution of the elastic problem in terms of propagators is given. The analysis shows that a nonuniform easy axis requires a careful experimental determination of the anchoring energy, detected by means of optical methods. Several particular cases are analyzed in the strong- and weak-anchoring situations.
